Oh, you don't need to do that. You _can_ gracefully extend the union, as
long as you are willing to accept that calls made using a discriminator not
known to the server you are calling will abort with RXGEN_SS_UNMARSHALL.
This is the moral equivalent of a call to an RPC not supported by the
server aborting with RXGEN_OPCODE, and is perfectly acceptable, given that
you shouldn't be sending notifications with unknown types anyway.
