Context: Our internal testing setup uses a minio instance so we can test against an actual S3 API, verify that signing URLs works as expected etc.

df31792 did not only update hyper-rustls and expose an option to use native or webpki roots, it also hardcoded the configuration to only support HTTPS without offering any way to configure this:

builder.https_only().enable_http2().build()

At least in some cases (like the one I outlined above), I think using .https_or_http() instead would be useful, so I would like to see it either made configurable (at runtime or compile-time), or just as the default to not break my testing setup right now (though that's a bit selfish lol.)
