You could, but since that's how Emacs worked for the last 11 years, I
don't see how such a claim would stand.

I tried that with different styles, including flex, and I still don't
agree with you about the need to reverse the emphasis.  So what you
think must be the default at least for me doesn't sound 100% correct,
as I find flex very usable for me with the current method of emphasis.

I'm sorry, but that's not how defaults in Emacs change, not because
you give me your word or describe what other applications do.  Not
when the proposed behavior is in such stark contrast to what we've
been doing for years.  We first introduce such a new feature as
optional, and later change it to be the default based on user reports
and complaints.  I suggest to do the same in this case.
