I think this depends on how you view limit: is it to limit the output
(roughly to run "head" on the output), or is to bound the amount of work
notmuch has to do (eg to make sure you don't get a long delay). Your
suggestion is definitely the former, whereas I am more worried about the
latter: limit in your definition could take an essentially unbounded
amount of time.

Best wishes
