env: follow up on argv0 setting feature

[Matheus Afonso Martins Moreira]

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

https://lists.gnu.org/archive/html/coreutils/2023-03/msg00002.html

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.

I waited a while and eventually sent an email about it:

https://lists.gnu.org/archive/html/coreutils/2023-08/msg00059.html

The maintainer noted that they expected this feature to be included
in the next release which would be focused on features:

https://lists.gnu.org/archive/html/coreutils/2023-08/msg00060.html

> The next release will focus on new features, and this

Since then I've been tracking commits to the coreutils master branch
but it appears the feature has not landed yet.

What happened? Was it rejected?
