Unfortunately yes. In fact, I quite recently found a problem in
Riverstone's SSR2000's which just drop host-unreachables on
tcp-loadbalanced connection.. However, we still need to ask the
question "do we keep finding workarounds for other peoples poor
administration/implementation of technical solutions?".. 

The technical solution for MTU problems is Path MTU Discovery. If a
vendor fails to implement, one should not buy its equipment. If an
end-user breaks his own connectivity, he/she needs education.

That would be the ideal world. In the less-than ideal world we have to
find a way to defeat the cluelessness (excuse the language) of vendors
and end-users.
