Which is what popular setup like create-react-app and alikes are against. It doesn't make too much sense for more heavy application like interactive editors to have multiple artificially split files just to conform with this limit.

You need to make a business case that your whole application is modularly composable.
Some application might fit under this umbrella, but there are other stuff that don't, like a pdf-render, or something like google slides, which as I just checked, the core editor js is bundled in a single js file and as large as 1.4MB.
And ofc you’d naturally just attribute this as an artifact of optimization, just as single-file packing was. Which it is, given http 2/3
Splitting probably makes sense only for an infrequently used feature, like video chat in an app like Gmail or Slack.
