In general, I see no reason for a modern RDBMS not to provide an email-datatype. IMV that's no different from other types which also could have been plain-text but are convenient to have datatypes for.
Being an open-source project I guess one must show initiative and start a discussion on -hackers to see what interesst there's in having one in core. I for one hope there will be.
