Not true.  Sane way: in absence of -of, of is guessed.  If you don't 
give an extension we recognize, either fail with warning or default to 
avi.  Add of=avi to your config for the old behavior.  What's wrong with 
that?
It does not support the "extension matters" paradigm either.  If you 
want to use arbitrary extensions, simply specify of explicitly.  Not 
difficult.
