As far as the regs go, is "MVFR" even defined? I kinda doubt it... it's
either below minimums (as prescribed by the overly complicated VFR cloud
clearance/visibility rules), or it's not.

True, being MVFR has no particular regulatory significance. But neither do
most of the other terms and symbols that appear in the government's aviation
weather products. Still, they have explicit definitions that are useful to
be familiar with in order to correctly interpret the meteorological
information that's offered.
