Of course - the (long term) goal should also be to change the
syntax of unmanageable commands so that they can be handled in BNF
without much trouble.

I mean regarding parsing.  If filters are universal, they
shouldn't be part of the command syntax, and the parser needs to
figure out which arguments are filters and which belong to the
command, e.g. by a rule that filter arguments must always be
placed before other arguments on the command line.
