Yes, probably working up to some degree. I do no know if this could help.

One issue is that f-id is not a ring homomorphism. So do I restrict to a
range of degrees, convert to vector spaces, and compute the kernel? I'm not
sure of the right approach.

Good question, and I don't whether the subring is finitely generated. I
want to compute examples — what's the subring in a range of degrees — to
see what's going on.

Dear John,
Wouldn’t be of some help to consider the kernel of f-Id (with Id the
identity map)?
Best,
