Networking for Arduino (Ethernet over USB, RNDIS, ECM, NCM) possible?

[TheRealSunnyalex]

Brief: is there a way to get the RNDIS or NCM class of TinyUSB running for Arduino? Is there a reason why these are not supported by the Arduino version of TinyUSB library (whereas WebUSB is supported)?

Long:
I just recently purchased an RP2350 board (pico 2W).

My final goal is to "host" a website on that device, make that device "register" at a Win 11 PC as some sort of Network Interface via USB and then being able to exchange data with the device via a Webbrowser.

I stumbled on Adafruit TinyUSB library, which should be able to achieve what I want with either RNDIS or NCM (I am not familiar with either of them, I only read that RNDIS is not recommended for new projects).

I also have the RPi debug probe.

Initially I started coding for that RP2350 with VS Code. However, frankly speaking, I was not able to get the TinyUSB library running (I found no "tutorial" or "example" simple enough to guide me through integrating that library into a project for the RP2350).
I then noticed that RP2350 can also be programmed by Arduino IDE and I noticed that there is an Arduino version of TinyUSB library.

Things started good and I got the WebUSB example running without any issues. Just then I noticed, none of the "Networking" USB device classes appear to be supported in the Arduino version of TinyUSB.
Is there a reason for that?
Will they be eventually supported in the future?
Is it possible to "manually" get them running?

Or do I have to revert back to VS Code and try my luck there?

Your feedback is very much appreciated.
