So in order to avoid the loss of trust chains because of no longer used=20
resp. lost email addresses it seems to make sense to add a user id=20
without email address to each key. This user id will always be valid=20
unless one changes his name, e. g. because of marriage. But even then=20
the user id could still be considered as valid; maybe people who=20
consider changing their name in case of marriage should add a comment=20
like "birthname" to this user id.
Are there reasons not to add a user id without email address?
