So what's exactly the deal with Jolt physics?

I have been developing in Godot for about 2-ish years now and whenever I try to use Jolt physics for a new project, I run into issues with compatability pretty quickly

Today I found out that apparently all types of physics joints are not supported in Jolt?

So I am curious on what Jolt is used for or what its intended use is, since I feel like I am doing something wrong
