Comment 10 for bug 158570

Max,

We plan to make both, name and displayname, required when activating a new PPA. This way users will be able to user any format of reference format for their PPAs. Existing and new PPAs displaynames will be editable as well.

The signing-key UID discussing is also relevant here, and using the PPA displayname on it doesn't look right even when it is mechanical (as they are now), even more when it becomes editable. That's why we are planning to simply use the PPA LP url:

{{{
Signing key for https://launchpad.net/~maxb/+archive/mercurial
}}}

And block 'name' changes on users who have PPAs (PPA name is already constant). Mistakes and typos will be much easily sortable by activating a new PPA (and subsequently deactivating the broken ones).
