there would likely be more able and willing development contributions

As I said in the linked comment above, I'm not convinced that this is actually true and we've yet to see evidence that it is true.

the problem absolutely is that Lemmy is written in Rust ... Then again with an attitude like this regardless of chosen programming language ...

I mean, didn't you just say it there? The problem isn't with Rust, the problem is with people, the resources available, the devs willingness to implement what you ask for and such. The problem sounds to me more social than technical. I really don't think the programming language is what is standing in the way here 😅
