I think it's unlikely but possible sure.

The change happened in KDE 4 which was released in 2008. The change
would break users of KDE3 which isn't supported anymore since 15 years
by now.
So the change would fix the behavior of users which are still on KDE 4
or 5
(Technically KDE Plasma in this context after KDE3) and those which use
the latest stable KDE Plasma 6.

I don't think there's a chance for that.

If you decide to install the change on Emacs 30. Do you want me to send
the patch again with the changes mentioned by you i.e. defcustom version
and type?
