Besides that, just now I also tried to do a remote --recv-keys on my own
key and I found that indeed the signature from Stefan was not attached.

Then I found this:

https://daniel-lange.com/archives/178-Getting-gpg-to-import-signatures-again.html

So it seems the default behavior of gpg command changed recently that it'll
stop to receive signatures besides the self signature to avoid DoS to the
keyservers.

https://dev.gnupg.org/rG23c978640812d123eaffd4108744bdfcf48f7c93

In short, now we seem to need:

  $ gpg --recv-keys --keyserver-option no-self-sigs-only $KEY_ID

To recover the old behavior to receive signs from others.
