I wonder if one could possibly take it like this (at least I try to do, but there’s some places when it doesn’t work.):
“Real” Macross Canon (aka, the non-existent “real events” that Kawamori indirectly refers to, which we can discard because we never see them) >> TV Series Canon (including OVAs) >> Movie-Retelling Canon (DYRL, BH, TFS).
So, if you’re in “Real” Macross, you watched the TV Series, and within the TV series, you knew that the movies had been made re-telling history (kind of how we would watch a documentary about Jack the Ripper which also shows scenes from Jack the Ripper movies). In you’re in TV Series Macross, you’re just watching the movies. And if you’re in the movies, you aren’t watching anything.
Now, “Real” Macross is a middle-man that we can cut out because “Real” Macross does not add or change anything from what we watch, hence, we would be taking the place of “Real” Macross, just without their history with which to verify facts and compare to.
Which would make TV Series the Main Canon, i.e, the facts by which everything else will be compared, and the re-tellings would simply be as their events were recorded in the history books, with some added flair from the director (The director of TFS could, perhaps, be a Ranka-fan but unable to make her a heroine using her real actions and personality, and thus changed a few things to make it viable. It would also explain the over-the-top-perfection of Sheryl, who would probably be nearly a saint to Frontier. Minmay would probably get the polishing treatment no matter who made the movie because she was that important to humanity and aliens first getting along together. If we got an M7 retelling, it would be very divisive in terms of Basara, those who thought him irresponsible and the zombie-fans who would treat him like a god). Hence, we could see the movies as the public perception of the Macross people (would also explain why so many battles were moved from deep space to Frontier; people probably remembered getting their city smashed more than some distant battles in space, and gets a skewed perception as to how large a percentage of the battles were brought to their doorsteps).
It would also fit with the Ranka-love at the end of the last Frontier episode. The people of Frontier really, truly believes that their (TV) Ranka is like Movie-Ranka, which would fit the innocent messiah much more than Ranka’s immaturity and single-minded focus on Alto. To them, Ranka thought equally about Alto and her brother. To them, Ranka and Alto were childhood friends because they knew each other before Ranka was famous. To the Alto-fanboys, Alto used his Kabuki to solve the mystery of Sheryl (also, the movie would address the doubts people had about Sheryl’s allegiances to Galaxy and Frontier). Even Brera gets even more cool super-soldier actions, to make his and Alto’s alliance against Grace in the last episode all the more sweeter (you know, the feeling of completeness when Badass Warrior acknowledges the main character and fights back-to-back with him).
These movie re-tellings would also be colored by what happened during and after the TV series. Sheryl might’ve gotten along great with Ozma, so she gets extra interaction with Ozma in the movie. Brera might’ve grown closer to Sheryl and Alto, which would add extra interaction between them as well.
This would also explain why Battle Galaxy got all the added thorns and spikes: It’s more villainous. Battle Galaxy, if the Vajra were out, was the face of the enemy to everyone who couldn’t access Vajra Network at the time (see also Hades from Disney. In Disney’s version, Hades looks evil. In Mythical versions, Hades is just as handsome as his brothers).
It would actually be kind of fun to see an analysis of how Frontier views their heroes if TFS was their take on the events of the series. (Lonely Sheryl versus Sheryl Who Wasn’t Completely Alone Until Grace Abandoned Her. Innocent Ranka versus Ignorant Ranka. Blatant Alto versus Subtle Alto…)
