Currently trying to port a web extension over to safari which heavily relies on the include_globs property of content_scripts. There is currently no alternative here.

One of the use cases here is to help collapse permissions.

If you have these two content scripts:
Code Block language
{
      "css": [ "style-a.css" ],
      "matches": [ "https://*.example.com/*" ],
      "include_globs": [ "https://a.example.com/*style=a*" ],
      "run_at": "document_start"
},
{
      "css": [ "style-b.css" ],
      "matches": [ "https://*.example.com/*" ],
      "include_globs": [ "https://b.example.google.com/*style=b*" ],
      "run_at": "document_start"
}


The permissions for these content scripts would merge into *.example.com, and the permission would be a clean host permission.
