If this is a listed feature of EPUB 3.2 and they are 2 or more Japanese rS
supporting this feature, the Director should not see any issue with it,
from my understanding.

Yes, I was about to say exactly the same.  So, I don't think many (any?)
features will be in danger.  It should not be an issue of support by all,
it's support by more than one.  Re Tate Chu Yoko, I know that we "do the
right thing" as well as do a number of other RS's in Japan.

Let's get the data first, and then decide if we have an issue (I'm betting
not).  If there are EPUB 3.2 required features that are supported by NO
RS's having a conversation about dropping (or ramping up support) does seem
reasonable.  Similar for any required features support by only a single RS.

Best,
