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
