I assumed this object would be an auxiliary thing, because that's all
that makes sense.

Making an LV2 plugin that doesn't actually use the LV2 methods doesn't
make any sense. It could technically have those fields but have them
not do anything and theoretically be a "valid" LV2 plugin I suppose, but
it's a completely braindead and pointless thing to do anyway, so who
cares...

If the motivation for this is the fact that this class already exists,
then simply make the LV2 methods call the methods on that object. The
"bypass LV2 entirely" thing you describe is crazy. No point in using
LV2 at all, that way. At best it's just being a huge pain in the host
author's ass for no reason.
