The Threadiverse is growing again, this time offering an effort to build a new Lemmy replacement from scratch, with API compatibility.
Seems like an interesting effort. A developer is building an alternative Java-based backend to Lemmy's Rust-based one, with the goal of building in a handful of different features. The dev is looking at using this compatibility to migrate their instance over to the new platform, while allowing the community to use their apps of choice.
I think how quickly this project has gotten to near feature parity is a testament to how slow Lemmy development has been. Think about scaled sort (a feature that has been hotly requested since the migration) and how long that took to get merged in. A sort should not by any means be slow to implement.

Sure, if the sort key is something readily available. But for scaled sort they have to compute relative size/activity of the communities the specific user is in. The cost isn't the sort, it's computing the metric.
Depends on amount of technical debt really. Sometimes rewrite is the only way. But in general fixing things can be done. It's just matter of time, focus and effort.
