Research direction
Start with the linked httpx connection-pool discussion and the referenced issue comment. Determine whether per-time-unit rate limiting is already supported or would require a new design; done should be a decided approach or documented answer to the request.

In this comment @florimondmanca suggests that the connection pool limits can be used to rate-limit the number of requests made. I can see, of course, how setting those limits will constrain the number of 'concurrent' requests made by httpx. However, what if I want to limit the number of requests made per unit of time?
Say the API I'm hitting allows 10 requests per second, I guess a naive approach would be to set the hard limit of the connection pool to 10 and asyncio.sleep 1/10 s after every request. Does that sound about right or am I missing something obvious?
