The problem with that rationale is if you're buying the Robotech DVDs and trying to call them Macross you've got another thing coming. The RT fans are idiots. They've bought the same poorly dubbed, poorly edited crap again and again, first on VHS, then DVD, and now a remastered DVD to "the director's cut" which is just adding half the stuff they cut to make it fit before. As a former RT fan, I can safely tell you that the quality of each successive "remastering" of Robotech, the quality of the product gets lower and lower. RT Remastered is plagued by some problems as fundamental as disc formatting and errors on disc.
Sure, TMS and Macross share animation, but there's a whole world of difference between the dubbing, the editing and the overall quality of the work.
This, to me, reeks of a Harmony Gold attempt to remove potential competition for their new Robotech series, which the guys on my website dubbed Shadow Farce before they changed the title from Shadow Force to Shadow Chronicles.
Mind you they'll probably whore the liscence to ADV once Shadow Farce goes under (and there is no doubt in my mind that it will flop abysmally and drag Harmony Gold into the red on project budget once more), or maybe if we're extremely lucky, give it back to Animeigo at a bargain price.
Either way we lose.
