Bundling is a practical, basic need, for acceptable load time. HTTP/3 may help there but I haven't seen it in practice.

Not having 100s of dependencies to bundle from is great too. In the jQuery era, you had jQuery, a few plugins, and the main js files. Now we’ve pushed backend’s logic in the frontend without the pragmatism of the tooling.

Your own code is typically at least a dozen modules, bundling is required even with zero dependency

I thought I read that HTTP/3 only helps with high latency connections that experience a lot of packet loss.

Sorry, I mean HTTP/2 multiplexing
