I don't know why that happens but I doubt it is because of a bug in Forge.

The (maintainer_can_modify . t) part of forge--submit-create-pullreq has been there for three years. It's also not something let-alist should concern itself with.

This is with freshly byte-compiled libraries.

Never-the-less, as with all mystery bugs, I recommend removing all relevant packages, exiting emacs, restarting emacs, and then reinstalling.
