I see your point about excluding 'Signing key' and I agree.
TBH, I prefer the former suggestion, 'Launchpad PPA at <URL>', because it pass the right message to the user 'Click on the URL to know what is that about.'.
No unstable, and sometimes meaningless, displaynames in the key UID.
I think that adding the repository URL as the UID comment would be nice, but since it varies according the PPA privacy, it's not a good idea.
