env: follow up on argv0 setting feature

[Matheus Afonso Martins Moreira]

About five months ago, I posted an env feature request on this list:
the ability to set the value of argv[0].

I also sent a patch:

https://lists.gnu.org/archive/html/coreutils/2023-03/msg00003.html

After some discussion, I was informed it was under consideration:

https://lists.gnu.org/archive/html/coreutils/2023-03/msg00012.html

> We're still considering and will adjust as needed.

Since then I've been tracking commits to the coreutils master branch.
I didn't see anything related to this feature in these past few months
so I thought I'd follow up here.

Has a decision been made?
