Having an "avoid-processing" option is a good idea. I'm not sure what
your proposal is for the old "avoid-resampling" option in daemon.conf.
I'd like to keep that separate, so that it only affects sample rate
conversion. The next best alternative would be to deprecate the option
and make it an alias for avoid-processing, and log a warning if it's
used in daemon.conf, with a message that tells the user to use avoid-
processing instead, and if the user actually wants to only disable
sample rate conversions, they should contact us so that we can bring
back the old option.
