Similar to Is it wise to remove redundant self-signatures from my PGP key? - I noticed that after a couple of years, and multiple key manipulation (I use keyoxide.org so my UIDs have multiple notations attesting different Internet identities) - I have a lot of self-signatures. Cleaning with --edit-key and clean as suggested in the answer to that question works fine.
However: my encryption subkey still has two signatures, corresponding to the time the key was first created and the time I extended the expiration:
❯ gpg --list-sigs 8B229D2F7CCC04F2

sig 8B229D2F7CCC04F2 2022-05-15 Michel Alexandre Salim <michel@michel-slm.name>
Is there any way I can clean this up too?
