Brought up by @jkrems on Twitter - do we permit these mappings? And if so, does that mean that a data: URI with a trailing slash is permitted as a folder mapping?

eg:

{
  "data:application/javascript,console.log('test');//null comment//": "https://site.com/"
}

would the above map any content after the data URI above to the local URL? And conversely:

{
  "x/": "data:application/javascript,//"
}

would the above map x/\nconsole.log('hi') into its executable data URI?
