Require `pip install httpx[http2]` for HTTP/2 support

See original GitHub issue

I wonder if we should consider having HTTP/2 be an optional requirement, rather than always-on.

I’ve been working towards minimal installs in other projects eg. Starlette (no hard dependencies) and Uvicorn - we’re planning to move towards pip install uvicorn for a basse install of just click and h11, and pip install uvicorn[default] to pull in websockets plus platform specfic stuff like uvloop and httptools. And generally with the other projects in the encode async space too.

We could consider having minimal and default install options with httpx too… eg:

pip install httpx - Just http/1.1 support.
pip install httpx[defaults] - Also http/2. Potentially http/3 and/or websocket support at a future date. Possible that hsts isn’t strictly a hard requirement either.

Any thoughts?

Yup, agreed after our discussions on #639. The off-by-default behavior is probably sufficient as a “this is edge stuff” flag. At least having it off by default protects our users from dealing with HTTP/2 issues when all they want is to make HTTP requests, regardless of HTTP/1.1 vs HTTP/2.

I’m going to suggest we drop this. Any thoughts?

Our HTTP/2 implemenentation has greatly improved, and even tho it’s currently not enabled by default I could see us switching that once we judge it to be sufficiently mature. I’m no longer convinced that “minimal installs” are worth the additional hoop for users to jump through and codebase complexity.
