Do you still posess all mail addresses you had 5 Years ago? Who does?
So what is the use of signing an e-mail address for infinite time?
For the service to be usefull the need to recertify after a period of time
If it works with expiring signatures as well I am fine about it.
But letting the authority's key expire (not revoke it!) was not a problem
I have several trust paths in my keyring that depend on expired CA keys and
thy work fine.
And if a user who relies on a robotCA signature gets the message:
"This signature is more than a year old and thus needs to be updated" it is
a good thing to happen.
