Another big caveat is that there isn’t data here on-site usage after first-load, which is a huge aspect of “single-page app” approaches.
Still, while you can be performant with frameworks (although even that top 10% isn’t super encouraging), the frameworks aren’t doing much to help what has turned into a bad situation. It mimics exactly what we talked about recently with accessibility. It’s not the frameworks “fault” exactly, but they are also the best positioned to stop the bleeding.
