photo-ID omitted when retrieving keys from WKD

[Piotr Morgwai Kotarbinski]

hmm: I don't seem to follow:
if a user decided to trust (to certain extent) some domain's WKS admins regarding key fingerprints (for example the user trusts that the WKS admins verify key fingerprints with members of their organization by some means of their internal procedures), it seems quite arbitrary to assume that the user should definitely NOT trust the same admins regarding photo-IDs verification (for example the admins may be comparing photo-IDs with photos from their HR DB before publishing to the WKD). It seems to me, that a decision whether to trust some WKD regarding photo-IDs should be made by individual users based on their knowledge/feeling about security practices in the given organization. Users can "store" such feelings in their keyring by either (l)signing the given photo-ID, leaving it as is, or deleting it themselves.

Furthermore, it may happen that some photo-ID stored in a WKD is signed by a 3rd party that is already trusted by the user. Stripping such photo-ID may unnecessarily conceal information that may be useful/important to the user.

Am I missing maybe some part of the story that invalidates my reasoning?

Thanks!



PS: Happy new lunar year to everyone! :)
