I am not sure to understand why you are doing it like this.
Shouldn't you just:
1. Don't advertise features you don't want to support
2. In server mode, save the negotiated features, and re-use it when
reconnect happens?
Also, I find "unmask" a bit misleading, why not something like "unsupp"
or "unsupported"?
Thanks,
Maxime
