If you don't mind, I'd very much like it back. It doesn't violate the RFC
(or its successors) so it's really PGP's problem that it doesn't comply
with the RFC in accepting such signatures. My rationale is that because
this key is for a laptop, and laptops are more likely to get stolen than
desktops, thus compromising the key, I can simply revoke the subkeys, and
keep the primary key, which would be on my desktop. Of course, since I
don't do that much key signing, I *could* use the primary key on my
desktop, but then I'd use my regular key, right?

If you'd like, you could even require --expert to use it.
