It's definitely been considered, especially since we've now bumped our
required versions. MySQL UUIDs, though, have issues when it comes to
replication. Ultimately, a post's GUID can't be considered globally unique.
Just unique across the site/network. Given that GUIDs are only used for
feeds, this is acceptable. If a plugin may wish to leverage their
"GUID-ness" for something else, then your mileage may vary.
