I don't know where you're getting your information, but those are the two default plugins (on Windows and everywhere else). They're hardly "not recommended" since they're the only possibilities.

That is generally semi-inaccurate, but I have no bandwidth to spend to cover how the SP works. Logically speaking it's an Apache module the same as many others and that's all that matters, it just happens to have a separate process that has to be running. The rest is beyond the scope of user documentation.

All of the SP relies on the remoting code. The listeners are an implementation detail of that code and are interchangeable to the SP. There are no examples other than the source code.
