Well... To this at least I can answer. Sure, it links a key to an email address. Yet, more often than not one knows the email address of the intended recipient (otherwise, how would he/she send the email?). So knowing an email address is associated to a key can be useful. About emails reused by different persons... AFAICT most major email services never re-issue the same email address twice. Which could be considered good practice. If one worries about an email agency stealing the email addresses, well... A signature on an email UID means "Yes, this key is used by the same person as the email address". So signing it "automatically" would not conflict with the meaning of the signature. Yet if the UID also includes a name, then it should be signed only after appropriate verification of the owner.
