Unfortunately, yes.
For what its worth, the implied criticism is valid: the road to complete the migration from Django templates to MFEs has taken much longer than anyone foresaw. The good news is that we’re almost there: in just a few more months it looks like we might be rid of all legacy pages.
(You’ll still need the legacy mechanism to style XBlocks - see this post I just answered - but that is a much bigger can of worms which we might - or might not - eventually solve with XBlocks 2.0.)
