It works okay in practice, too.

You are correct about misconfigured networks.  In my experience,
the only reason to ever reduce the MTU is to work around a problem
discovered in someone else's network (not my local segment).  Fixing
the problem by getting someone else to fix their network is generally
too hard.  If MTU == MRU was forced behavior, the viability of this
workaround would be removed, one less tool in the toolbag, so to speak.
