Revoking a Model Signing Key


I have raised a support ticket about this, but thought I would reach out here to see if I can get any good suggestions in the meantime.

I created and registered a Model Signing Key to a store Brand Account that I wish to revoke or disable somehow. After a bit of googling, it doesn’t seem like it’s currently possible via standard user tools and API.

Here are some related posts on this forum:

Has any progress been made ? Can I just register a revoked version of the key [ after doing a gpg revoke operation in gpg --homedir .snap/gnupg/ ] ?
