Idk, the general javascript spinner situation is beyond normalized at this point. I think mainly driven by React and other large/overkill JS frameworks. I avoid JS/TS heavy stuff so I don't really know but that's largely the impression I get. The whole thing reminds me of dialup era internet were we all were watching progressive JPGs load on a slow connection despite the fact I have fiber. I can't believe anyone is Ok with that UX, I don't see how any framework choice justifies introducing that type of behavior.
