If set-variable does not tend to consult the "customize" data
structures in other circumstances, it would be unexpected if it did
in this case.  I do seem to remember, though, that set-variable
declined setting a variable to values opposed to any possibly
customize declaration.  So perhaps making set-variable do pretty much
the "set for current session" operation procedure of customize would
be sensible behavior.

That does not imply that the current behavior would be a bug, simply
that it might make sense to change it (along with its documentation).
