Because mysql has a normal shell.

I think the scheme used is better than using just uid.

I also wonder about why some of services have valid shells. I know that
Tom Lane indicated that postgres has a shell intentionally as it helps
to be able to su to postgres to do some tasks. Probably mysql is expected
to be used the same way 9as tom packages both). But there were other ones
that seemed suspect to me. The ones I wasn't using I changed to have
a shell of /sbin/nologin.
