The `.aclose()` method has a comment saying ""Close transport and proxies"" - I'm not using proxies, so the relevant implementation seems to be a call to `await self._transport.aclose()` in https://github.com/encode/httpx/blob/f932af9172d15a803ad40061a4c2c0cd891645cf/httpx/_client.py#L1741-L1751
The transport I am using is a class called `ASGITransport` in https://github.com/encode/httpx/blob/master/httpx/_transports/asgi.py
The `aclose()` method on that class does nothing.

When called from a template it's likely the intent will be to further loop through the JSON data returned. It would be annoying to have to run `json.loads` here.
Maybe a `.get_json()` method then? Or even return a response that has `.json()` and `.text` similar to `httpx` - or just return an `httpx` response.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",681375466,

If a plugin wants to get back the first five rows of a table, it will need to construct a URL `/dbname/tablename?_size=5` - but it will need to know how to turn the database and table names into the correctly escaped `dbname` and `tablename` values.
Here's how the `row.html` table handles that right now: https://github.com/simonw/datasette/blob/b21ed237ab940768574c834aa5a7130724bd3a2d/datasette/templates/row.html#L19-L23

Hard to be sure one way or the other. I'm worried about logging middleware triggering twice - but actually anyone doing serious logging of their Datasette instance is probably doing it in a different layer (uvicorn logs or nginx proxy or whatever) so they wouldn't be affected. There aren't any ASGI logging middlewares out there that I've seen.
Also: if you run into a situation where your stuff is breaking because `datasette.get()` is calling ASGI middleware twice you can fix it by running your ASGI middleware outside of the `asgi_wrapper` plugin hook mechanism.
So I think it DOES execute `asgi_wrapper()` middleware.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",681375466,
