let id = 'abc';

It seems that this feature require us to do some extra work like scope analyze, name resolution? I am not sure if swc has been did such work.
Also should we need to support such dynamic import?

fn a() {
  return 'fs';
}
const page = import(a());

The issue title could be misunderstood. I think we were talking about supporting something like

const page = import('./src/pages/${name}')

We don't actually care about what the real value is of name, which will be decided in runtime.
Its like the glob import of vite.
