I'm not sure about the performance characteristics, but to answer your
other questions: I think an IN-clause like query is in the roadmap
(can't remember where I read this).

And you may be able to avoid hard-coding client_id into your views by
using the json collation order.

You'd simply use an array like: [client_id, another_value] as your
view-key, and then use start-key and end-key to return just the rows
per client.
