I know we are never going to be able to stop everybody who _really_
wants to shoot themselves in the foot from doing so, but I wonder,
perhaps if there should be "something extra" that needs to be done to
manipulate the size of volumes with filesystems on them (i.e. probe
the lv to see what's on it) directly (i.e.  lvreduce, lvexpand).  This
would of course be used to encourage the use of the convenience tools
like e2fsadm.

Perhaps an environment variable or an "expert switch" on the command
line or something.  Not using the switch or setting the env. variable
would cause a probe of the lv and if there was found to be a
filesystem on it, it would prompt the user to use a convenience tool
(for that filesystem type) to perform his task, or set the
switch/variable, if he really wanted to go ahead.

Or maybe this is all just too much handholding.
