The current release of Org is meant to be compatible with the last
three major releases of Emacs.  That is, as of now, 28, 27, 26.

See https://orgmode.org/worg/org-maintenance.html#emacs-compatibility

If the current release is de facto compatible with older Emacsen and
a new release will change this, yes, let's announce it in the release
notes.

We can also send an email to the list using the "X-Woof-Change" to
announce this upcoming change for the upcoming release.

For example, the current release of Org (9.5.4) is compatible with
Emacs 25.1, as Ihor noted.  This is older than Emacs 26.  If for some
reason Org 9.6 only supports Emacs >=26, let's announce it on the list
and add an entry in etc/ORG-NEWS and orgmode.org/Changes.html.

I think doing this manually is fine.

Bug fixes from the maint branch should never change the compatibility
status of Org.

Evolutions on the master branch can change the compatibility, but not
break the global promise of being compatible with the last three major
releases of Emacs.
