I've done something similar with a CAD app, where I've used AI tools to package it as a Nix flake. It's a really good format for wine packaging since it makes it so easy to patch wine in ways that would never be accepted upstream, and it makes launching it just one command vs needing to deal with other people's potentially broken wine prefixes.

Yeah, completely agree.

I absolutely love Nix Flakes; they feel, to me, like what Docker was supposed to be. A little self-contained packaged environment that gives you a place to do any kind of custom hacks deterministically.
