New submission from Alix Lourme firstname.lastname@example.org:
Currently, the Request (https://docs.python.org/3/library/urllib.request.html#urllib.request.Request) send header keys in Camel case.
This is a choice strategy (no problem with that) and even if headers should be considered insensitively (RFC 7230 - 3.2. Header Fields: https://tools.ietf.org/html/rfc7230#section-3.2), this is not always the case.
The fact that header keys are "rewritten" (in Camel case) could occurs complexity in troubleshooting (for sample: https://github.com/probot/adapter-aws-lambda-serverless/issues/62).
Having a note/mention about that in documentation would be nice.
PR will come.
