I'm not the person you are asking but the point of this whole thing seems to be as a test for how possible it is for an LLM to 'vibe code' a port of this nature and not really because they care that much about a port existing.

The fact that they haven't done the port in the normal way suggests they basically agree with what you said here (not worth the ROI), but hey if you can get the latest AI code editor to spit out a perfectly working port in minutes, why not?

FWIW, my assessment of LLMs is the same as theirs. The hype is far greater than the practical usefulness, and I say this as someone who is using LLMs pretty regularly now.

They aren't useless, but the idea that they will be writing 90% of our code soon is just completely at odds with my day to day experience getting them to do actual specific tasks rather than telling them to "write Tetris for XYZ" and blog about how great they are because it produced something roughly what I asked for without much specificity.

Doing the second part is to my understanding actually the purpose of the stated task.

I'd like to use the same UI on all platforms so that we can do some things better (like localization in the text window and resizable text) and my preference for that is GTK. I tried doing it myself, got frustrated, and stopped because there are more important things to work on.
