type: module should also enable experimental-json-modules

[haraldrudell]

When Dennis Ritchie came up with the shebang in 1979, he did not consider Node.js v12.0.0

So on the shebang line #!/usr/bin/env node you cannot provide arguments

If you do a different shebang line, it is no longer portable to macOS or Android

Therefore, adding type:module to package.json should enable every reasonable experimental module feature, in particular experimental-json-modules if it doesn't break us, it will make us stronger

People who do not want this behavior should use an intermediate script or custom command-line like json importers have to do now

This is by design. If json was supposed to be enabled with modules by default we wouldn't have a separate flag for it.

I'm sorry, but this is by design. There's also a good chance that experimental-json-modules will go away or change dramatically, because of WICG/webcomponents#839. See also nodejs/modules#427.
