Never mind the above, this is only valid upon startup of a client
connection. After that, clients will have to specifically query for
variables, so the impact of additional variables will probably be
limited here.

The question remains whether the place to add additional 'variables'
should be in the driver or in the clients. I prefer the latter for the
already mentioned reasons. In addition to that, it will be clear what
the origin of such 'variable' is.
