This was recommended in #90309, and @serhiy-storchaka, @encukou, and I all concurred that this method should be deprecated as it's not used (according to searching GitHub) and likely was created when <script> support in browsers was not common which is no longer the case.

   IMO <script> support was common, but it was still common practice to include the “hiding” comment.
   <!-- begin hiding is still valid JS.

   I never concurred with the deprecation. What's the reason to remove this function again?

   Can we soft-deprecate it instead?

   The problem is that it is almost not used, at least we have not find any examples in open sources. If we have no examples of use in real code, we cannot be sure that it works correctly. We cannot even be sure what is the purpose of it. We cannot maintain it.

   OK, looking more into this, I see the function doesn't work correctly unless there's only one key/value pair.

   I withdraw my objection.
