Still think it's best to continue with a real-case scenario, discussing

Here is a non multi-mode real case:

  1) goto arbitrary Info page
  2) narrow to a region
  3) widen

You will get the whole info manual. Hard narrowing will allow widening to
original page in step (3).

Don't see why info couldn't care for that - for example by indexing previous narrowing and re-narrow following widen if appropriate.

May think of nested narrows that way, which wouldn't require changes of Emacs core.

But info seems a special case anyway, while a true multi-mode really being at stake. Instead of diving into info now, suggest to continue with a multi-mode issue.
