Do you really mean `setq' (i.e. something outside custom or even
outside set-variable) ?

Especially since the toggle function called by the setter does such
a `setq'.

Huh?  Those variables are needed for other reasons, not for custom.
There simply needs to be a place where we store the current state
of those minor modes.  For some minor modes, we can use things
like (member foo bar-hook) or somesuch, but in general we just
need a minor-mode variable.

Furthermore, AFAIK, custom already does not need the variable: if you
provide a setter and a getter that don't use the variable, it won't
use the variable.  There might be a few places in custom where
this is not quite true but it should be easy to fix.

You also want to "remove" non-existent variable like stefan-test-1 ?
