If I get this correctly, this has an interesting effect: If Django 1.9 supports API Target Versions 1.7 and 1.8 at its launch, then it must also support them for its lifetime (dropping them would be the kind of change we don't introduce in minor versions). 1.7's API would need to be supported as long as 1.9 lives. This, essentially, makes every Django release an LTS.
I suppose many users would be happy about that outcome. Contributors, less so. -1, Shai.
