Comment (by fabiankaegy):

 My problem with this approach is that we specifically advertised the post
 type support editor sub property in WordPress 6.7 for the default
 rendering mode. So there is code out there in the wild where 3rd parties
 are using that today.

 By releasing 6.9 as it works today (even if we annotate it in the dev
 note) those sites will not have notes support on those post types. So
 without having done anything wrong they don't get a prominently
 highlighted feature of the release unless they update their code that we
 told them to include before.

 However I do also see that we are likely just too late in the 6.9 cycle to
 safely land this...
