Doesn't matter what I think here, and I may
be missing your point.  But, in case it helps:

1. :set takes care of what you say.  And it's
   specifically for (1) only setting and (2)
   only user options.

2. I don't see how a watcher provides users
   with a command, to interactively toggle
   the value.

3. Cf. the suggestion to use a minor mode.
