In custom elements, is it best to create one MutationObserver that handles every instance of the custom element or observers per instance, then set up and tear down the observer inside the custom element lifecycle?

I find it wild that the Brotli RFC includes C code with a function with the non-descriptive name of "Ferment" and also doesn't describe its intent.
