is this abandoned or still something you are thinking of landing?

The rework towards lib is paused, since I'm focussed on other topics.
I still think it's a good idea and in case of having some time I would work on it.
Meanwhile there are some conflicts to be resolved.

In case you want to make a PR, I would be very glad and commit myself to quickly do the review and make a new release.

I have a lib extracted and working but I need to review the code carefully and test it. I'm going away this weekend but I'll send a PR early next week. I used Claude Code AI so if that kind of thing bothers you you can just reject it. I'm scratching my own itch because I want a daemon that I can hit with rest calls to manage ports and such. It's a huge PR though... if you want you can see the WIP at https://github.com/gherlein/ntgrrc

I have no objection with you using AI ... just looking at the result.
From other projects I know, AI agents sometimes leave dead code etc. ... such should be eliminated obviously.
