You should extend existing encodings only in a way that would not break
interoperability with existing clients and servers. E.g. you send some
special pseudo-encoding code in SetEncodings, then the server may start
using your particular extension to the Tight encoding. Note that such
special pseudo-encoding code should be registered in the RealVNC's
official RFB specification.

As for extending the Tight encoding, I'd prefer that it would not be
called "Tight" after any extensions or other changes have been
introduced. That's just to prevent unnecessary confusion.
