Currently biome lint blames only the Deno variable:

  ✖ The Deno variable is undeclared.

     7 │ 			location.hash,
     8 │ 			process.env.HOME,
   > 9 │ 			Deno.env.get("HOME"),
       │ 			^^^^
    10 │ 		].join("\n"),
    11 │ 	);

  ℹ By default, Biome recognizes browser and Node.js globals.
    You can ignore more globals using the javascript.globals configuration.

Is there a way I can reject every globals including browser and Node.js? In ESLint with no-undef: "error", all global variables are reported (got from ESLint Playground), and that's what I want:

 3:1 'requestAnimationFrame' is not defined.  (no-undef)
 4:2 'alert' is not defined.  (no-undef)
 6:4 'status' is not defined.  (no-undef)
 7:4 'document' is not defined.  (no-undef)
 8:4 'navigator' is not defined.  (no-undef)
 9:4 'location' is not defined.  (no-undef)
10:4 'process' is not defined.  (no-undef)
11:4 'Deno' is not defined.  (no-undef)

In ESLint, specifying /* global document, process */ at the top can suppress the errors for document.title and process.env.HOME.

I checked #1147 and #2074, and I think these issues don't fit well, so I'm creating this. Feel free to move this into a Discussion.

Why

To prevent:

using window in Node.js context, or process in Deno or web
using status variable without declaration (to avoid using window.status mistakenly)
using globals without explicit notation
