Lots of changes break workloads. The question is how common is a
particular change. Heck, people tolerate random perl and pythons
scripts breaking when new versions are released, and that's
considered... OK.
Given that other Linux distributions have been using the "new" su, I
very much doubt that many people will notice. For that matter, I set
my PATH in .bashrc, so the PATH is *always* reset in a new shell, and
in fact, I make sure I know I'm root so my .bashrc sets the prompt
like this:
<tytso.root@cwcc> {/usr/projects/e2fsprogs/e2fsprogs} (next)
1130#
(And in fact it does this whether I use su or sudo su. So I didn't
notice at all.)
Anyway, it's ultimately going to be up to Andreas as the Maintainer,
but perhaps you should try to craft some suggested changes to the
News.Debian.gz file, keeping in mind needs to be *short*. You may
find that it is harder than it seems to write something that is
generally applicable and useful for most users.

This doesn't belong in documentation for util-linux, and is
*extremely* specific to what you are trying to do.
As it turns out, I do something very differnt which is my .bashrc will
run ~/.ssh-setup, which looks for existing ssh-agents or gpg-agents,
and if it one doesn't exist, it will start one, e.g.:
ssh-add -l >& /dev/null
if test $? = 2 ; then
echo "Starting gpg-agent...."
/bin/rm -rf /tmp/ssh-$USER
gpg-agent --daemon --enable-ssh-support --sh > $HOME/.gpg-agent-info
. $HOME/.gpg-agent-info 2>&1 > /dev/null
fi
(This is only part of a 40+ line script; just to give you a flavor.)
So there lots and lots of different ways of solving these sorts of
problems, depending on what sort of requirements you might have.
(Mine are designed to work in a very large set of environments, not
all of them running Debian, and for that matter, not all of them are
running Linux....)
We can't really give these sorts of tips in the util-linux
Documentation.
