Things have been stable for a while now. We haven't had actual churn in years.
But given that there has not actually been progress either, my guess is that this is a temporary situation.
Either way, Svelte is one of those things that promise some real progress. Not one of the things that have the same amount of problems, but in a different configuration.
I came across an old graphics project I'd made for Windows/DOS around 20 years ago. Within about a half hour I was able to compile and run it on a Linux machine with Wine, installing the latest version of the compiler and dependencies.
I can rarely get a 6-month-old JavaScript web project to compile and run this easily. Churn in node versions, npm/yarn versions, dependencies being abandoned, superseded, dropping backwards compatibility.
