why is that bad? "foo" just just be "./foo", right?

"computeValidImportSpecifier" => "computeURL"?

I don't see why this is necessary. See comment in changelog

Don't you want an exception scope for this?

Please describe why we're doing this? E.g, to be compatible with web. And why the web does it

Uhh, I don't think there's any non-internal exceptions that can be thrown right now but maybe it's good practice.
