A, C, N, p already work
[10:26] -ChanServ- Mode lock on channel #test changed to +nprtACN.
a, o are channel status modes they can be set with xop functions
y is not documented as a supported Unreal mode, it is a module mode and since Anope does not support modified ircds you won't see +y any time from the dev team
might be possible in a module, I would have to look to see if one could extend the struct to add new entries
Fixato.. yeah I am looking into it, probably work like /cs ban does now when I am done
