I suppose that most beneficial picotcp feature is TCP support.
Working with picotcp v1.7 I have used tcp examples from
https://github.com/tass-belgium/picotcp-modules

It looks like that the tcp code does not work "as-is" after switching from
v1.7 to v2.1 so I have disabled it.

At the moment I have no good idea on picotcp integration next step.

This year I have faced with iPXE (https://ipxe.org/) as a user.
iPXE just works. It supports TCP and IPv6. It uses GPLv2.
May be iPXE would be a better choice?
However, I have not looked at the iPXE code yet.
