What about a name which says that this has to do with size of 
the standard bitmaps, e.g.

I don't know.  You can ask address@hidden if they are on the way.

I don't see how that is necessary.

(set symbol value)  -- but don't do that ... see my comment below

I think that set-fringe-standard-bitmap-size should be interactive.
You can then use a lambda form in the :set of the above defcustom to
call it with the required parameters, something like.

        :set (lambda (symbol value)
               (set-fringe-standard-bitmap-size value))

Why is this function removed ?
