No, you said that NUMCOLORS is known to be broken in a very specific
case. In the general, non-RemoteDektop case, it works. Can you
guarantee that for every non-palettized display, it will produce the
same number? Because otherwise you're changing the current behavior
for people who's not affected by the RemoteDeskopt-related bug.
