I see what you mean. Yeah - some duplication would be unavoidable in
this case - and while it might be acceptable in case a client wants
deep customization of the generated bindings, it might be perceived as
overkill in case of "simple" filtering.

This is also an idea that we have considered - e.g. in addition of
having a configuration file, have some sort of dry-run mode which will
just emit a configuation file, no sources/classes
