In a sense they do more than you want. They will provide the ability to 
set values much faster than anything using an FK constraint, I expect, 
and without having to use any explicit constraint.

Sure. Go for it. As far as enums go, the only cases I can think of where 
that will have any application are:
. you don't use enums because you want strictly vanilla SQL, or
. you don't use enums because you want to be able to alter the set of 
allowed values arbitrarily.

That still leaves lots of applications (e.g. those I work on in my day 
job) that will benefit from enums.
