Yes - it is covered by that. I do build facades for apis that don't have good client libraries, but for things like s3, or stripe - with solid libraries I don't.

Even when I build those facades I don't mock them out - I just rely on VCR.

I've never used test server like pytest-httpserver. I don't think that would buy much vs using stubbing your low level network libraries like VCR does. The killer feature of VCR is that it records the real network calls on first usage. If pytest-httpserver can do that in a proxy mode it seems like a good way to go though.
