Hi Andrew,

A key owner can (preferably automatically) create a “self-identity” on her
primary key consisting of a well-known string that contains no personal
information. To avoid breaking legacy search-by-id systems this string should
be unique to the primary key. I suggest using
“fpr:00000000000000000000000000000000000”, where the zeros are replaced by the
fingerprint of the key. The self-identity (and any revocations on it) can then
be safely distributed by keystores that would otherwise refuse to distribute
personal info.
Minor thing: I suggest using
"openpgp4fpr:00000000000000000000000000000000000" instead of "fpr".
That'd make the User ID a valid URI as "openpgp4fpr" is an assigned URI
Scheme, see:
https://www.iana.org/assignments/uri-schemes/uri-schemes.xhtml
Probably the cleanest solution (suggested by others) would be using
direct key signature (0x1F) [0] and avoid User IDs entirely. Your
suggestion Andrew has the benefit that it's immediately backwards
compatible with software "in the wild".
