Is it only me, I'm lost for what good thing we're doing this
discussion. I've never heard of single complaints from users nor
authors not to propagate from body.

I understand sometimes we need to sacrifice web-compat and thus users
and authors for bigger benefits, but I do not see single benefits in
this case. Can someone please explain?

We could possibly have it turned on to default in the certain region we're expecting the issues for ~10% of users initially (I believe Blink has done this with other changes recently).

That said, it's understandable if this isn't possible for your teams either, just wanted to get it on record that we won't be able to do this for the foreseeable future.
