I get it, there are heaps of NodeJS systems out there. Both Deno & Bun claim to be an improvement over NodeJS and then invest masses of time to be compatible with it.

I never liked NodeJS and I would much rather prefer a clean room JS environment with absolutely no explicit NodeJS compatability. 100% support for Web API specs would suffice.

Why can't Deno or Bun release a slim version and then a compatability preserving version for those folks who require it?
