What is the reason that you could not retract this package instead?

Before deleting the project, you can publish a final release version that retracts itself and all prior releases. If you fetch that final release itself through proxy.golang.org, pkg.go.dev should pick up the final retraction.

Done.

Hmm, you might want to retract a range ([v0.0.0-0, v0.1.0]) instead of pointwise pseudo-versions.

(https://pkg.go.dev/git.sr.ht/~koukas/go-managesieve is still showing a non-retracted -befeae0 version.)

All versions are retracted now. Thanks for your time!

Thanks for following up! Do you still need the package removed outright from pkg.go.dev, or does the retraction notice suffice?

(Note that removing a package from pkg.go.dev does not necessarily remove it from proxy.golang.org; see the FAQ at https://proxy.golang.org/.)

Please remove it completely, as there is no value in the documentation being available.

Done.
