How can I access the actual request body then? I think this should be handled transparently.

This only adds documentation for the existing behavior, accessing the request body is not part of this 👍 (see also #104 and #105)
That being said and given the current architecture, I think it's very reasonable to handle this explicitly. The documentation explicitly states why the consumer of this lib is in control of this behavior. (see also #47)
Note that I'm not saying this has to stay that way, but I'd rather discuss this in a separate feature ticket instead (BC break ahead). Do you feel like filing one? 👍

If I write code like documented now, how does reading the request body work then? Do I have to find it out manually and discard the first expect 100 request?

See the existing and the updated documentation: The Request implements ReadableStreamInterface, so you can read the request body by awaiting the data events and wait for a final end event.
Note that this is somewhat limited until #104 is resolved, which is something I'm currently looking into with @legionth 👍
Note that this is actually only a single request, so nothing is being "discarded" here.

@clue Remembered it wrong, thought expect-100 would send the request headers again then.

This should probably update $lower, too?

The $lower is only used within this method, so it's not needed anymore after this assignment.

This needs a strtolower call for $this->getHeaderLine("expect"), see https://tools.ietf.org/html/rfc7231#section-5.1.1
The Expect field-value is case-insensitive.

This should also check the protocol version, as it must return false for HTTP/1.0.
A server that receives a 100-continue expectation in an HTTP/1.0 request MUST ignore that expectation.

This simple PR makes sure we always match header names case insensitive.
Also adds some documentation for the existing methods.
