Yes. Especially regarding expiry this is neccessary. We have a default expiry 
nowadays and that needs to be extended automatically through WKD.

There is a task for that:


You can "force" a WKD update through:

gpg --auto-key-locate clear,nodefault,wkd --locate-key aheinecke at intevation.de

Yes ideally both should be combined. I'm still in favor of having dirmngr 
handle refresh through WKD or Keyservers randomly in the background. But we 
probably need the planned keyring controller process to control that.

Currently I guess it's the response of the client (MUA) to trigger refreshs.
