Key bindings in the global keymap were _always_ overridden by local
bindings.  That's how major and minor modes define key bindings that
override the global ones.  There was never a version of Emacs where
this wasn't so.  So if you think Emacs 28 worked differently, there's
some confusion and/or misunderstanding here.  Perhaps "C-x M-y" was
simply never used by any local binding before, but is used now?

You can't.  If there's a local key binding that gets in your way, you
need to unbind or rebind it (in a mode hook, for example).
