Obsoleting such a veteran feature needs a very good reason, because it
causes annoyances across the community, as it's most probably is used
in a lot of places outside of the Emacs tree.  If the only reason we
have is that there are some disadvantages in some corner cases, it's
not enough to obsolete the form, IMO.

Why would it be unsafe wrt redisplay?
