The feature to update streaming api filter predicates has been put on
hold for now. It is still desired, but not in the active development

You can backfill with the REST API, as you suggest. Or, you could
reconnect every few minutes on the Streaming API. It might be best to
have two streaming API accounts -- a /shadow stream that is long-lived
and /follow stream that you reconnect with every few minutes when a
new user is added. You can migrate accounts from the /follow stream to
the /track stream once an hour or so. If the /follow stream runs afoul
of a rate limit, at least the /shadow stream is still connected.
