But autoload does know whether there is a :setter, so it can decide whether
to put a custom-autoload, thus informing Custom opf whether or not the
package needs to be eagerly loaded.

What good reason could there be?
[ The same question applies to most other autoloaded defcustoms and
defvars, I guess. ]

AFAICT the answer depends on what is the intention behaind
the ;;;###autoload cookie used for those vars that don't need to preload the
package (and that don't have :setters either).
