Good question, In practice all our current implementations do.
The benefit is that it is possible to trace a message name in the
logs, however there is nothing (AFAIK) in the functionality which
depends upon the name staying the same. Each cycle of activity on a
Mail object begins with getting the name (or list of names) from the
repository, and any Store should (but may not) mark the end of a
cycle.
I guess you have to weigh up the cost of developing the code to keep
the name against the risk of name changes breaking something.
JCR assigns an internally generated UUID to all "referenceable" nodes.
This would be a perfect message key for a JCR based mail repository,
since it is guaranteed to be unique within a workspace, it enables
very efficient message lookups, and it allows all sorts of other nice
things like hard references, etc.
