Ironically, given the chatter in this thread, I'd say this is a problem very solvable by LLMs. The Svelte language is well defined, the JetBrains API is well defined. No reason why a plugin couldn't be LLM generated.
Yes but if you're using LLMs then surely something with more data available will produce better results?
Seems like a separate issue? I also wouldn't assume that. Svelte is faster and smaller than React, even with all the training data in the world there are still non-negotiables.
