It would change the current behavior. Please, try it using --spice-preferred-
compression. Currently (v0.12.6) it changes the compression for the connected
client and for the future ones as well.
I don't think that we should do the move & change of behavior in one step. That
is reason why I suggested to add the line, instead of replacing it.

Of course, each of display channels can have different compression (it is
possible now with the current git master). I think we should also remove the
compression from RedWorker at all.
