I've done that.

Yes, I saw that part of `set-variable'.  Probably, I'll add a piece of
:before or :before-while advice to `custom-set-variable' to do this in
my init file.  There are so many setq's in the init file, most of which,
I'm sure, are for options, that it will take me a while to migrate them
to this modified `custom-set-variable'.
