That's not the reason: we will apply the change to master without any
delays.  The reason not to install this in Emacs 30 is because Emacs
30 will be released VSN, and we don't have any time to get feedback
from people who might be adversely affected by this change, even
though we consider such breakage unlikely.  Installing on master
allows us ample time for collecting such feedback, or deciding by lack
thereof that the change cannot break anything.

In which case this is not urgent, and installing on master should be
enough.

Thanks.
