The whole point of quoted data is that they are not evaluated, so I
see no benefit at all to the fact that keywords are self-evaluating.
In a quoted context, I can just as well use symbols, with whatever
syntactic form you want. Some people might prefer colons:, others
*stars*, and still others <<ducks feet>>.

Since others have asked also -- the paper Classes and Mixins (Flatt,
Krishnamurthi, Felleisen, POPL 98) elucidates this in (a little) more
detail on the first page. The same goes for optional arguments.
PS: Since this is really diverging from SRFI-13, I think it would be
best to take further messages on this to c.l.s.
