In my book, that's a configuration change.  It might be made with the
intention of reverting to some previous configuration at some time in
the future, but a configuration change nonetheless.

It sounds like the claim here is that there are knobs whose initial 
settings are presumed to persist as part of system configuration,
but for which any "tweaks" are forgotten.  Those are two different
knobs, should be clearly identified as such, and their relationship
formally spelled out.  Depending on the complexity of their relationship,
it sounds like you may be asking for THREE objects (not all in MIB
modules, of course):
   - the persistent configuration parameter, Netconf or whatever
   - the writable "tweak" knob, whose values might potentially
     be constrained by persistent configuration
   - the read-only operational value, which would be some
     function of the configuration, the tweak knob, and heaven-knows-what
     else.
