Naive question, but is that dictated in the spec? Probably?

Just wondering that, since Deno is rewriting all of npm anyway, it would have been a great time to revisit some of these historical script-y design decisions, to make JavaScript/TypeScript-at-scale suck less.

Granted, probably too late now, but as-is neither of Deno's url-based imports or sandboxed-by-default changes has seemed worth the migration cost.

But, if they also made something like "everything hot reloads for free" level ergonomic/platform changes, then yeah, I'd be hopping over.
