As you said, 'ideally'. If some library tester not involved in the
library development wants to use the utility it would be nice to
report those warnings and error.
I would rather put assertions in the switch cases for unimplemented
filters, or removing them from 'GNU_longOptions'.
The primary function of pdf-filter is to serve as an utility, and not
as a test tool. I think that we should not change its interface.
