Speaking as one of the wg co chairs:

You are suggesting much the same as draft-ietf-sidr-bgpsec-pki-profiles - defining a new EE cert profile.

This draft would have to say that it is updating RFC6485(bis).

Which means making clear what the additions/modification/deletions are.

So that implementations know how to interpret these new certs when they find them in some repository, it must be possible to distinguish these new EE certs from other EE certs.

Etc.

And the wg would have to agree on the changes.
