Another thing I'd like is switches on a TC to determine what is reported and whether or not to trick the camera, like the Kenko Pro DGX TCs do. When no reporting is used, one might still want the identity of the lens changed in the metadata to reflect the presence of the TC, so you can tell when it was used. It might also be useful to change the identity of the lens by the TC to allow separate MFA settings for the lens when used with the TC.

That's not how it works.  TCs don't report to the camera, they report to the lens, and the electrical way they report only supports either a 1.4x or a 2x.  So, now the lens knows its attached to a TC (or it doesn't in the case of TCs that don't report), and it's up to the lens to report that to the camera.
