Yes, please do. Because:

I could reproduce it locally. And I could reproduce it also with another
backend, "~/.authinfo". However, if I start a new Emacs session,

(auth-source-search :host "example.com" :user "bob")

returns a valid result. Don't know whether this is a bug or a feature; I
let it to you to decide how to handle. The original bug in this report
("auth-source does not support creation with secrets provider") seems to
be solved, so I'd like to close this.

Yes. But deletion is not supported by any auth-source backend. So I
would prefer if we handle this in another bug report, if the
functionality is missing for you.

To be honest, I'm undecided whether deletion makes sense in auth-source.

Best regards, Michael.
