Comment (by fabiankaegy):

 The reason why this became an issue now and why I would suggest we fix
 this in time for WordPress 6.9 is that in 6.7 we shipped the editor post
 type support sub-key
 {{{default-mode}}}. And now in 6.9 we are adding the {{{notes}}} sub-key.

 So when there is existing code out there that adds the {{{default-mode}}}
 it now causes the {{{notes}}} support to be overwritten.
