That is correct, it was added in <https://issues.guix.gnu.org/64765>
because commands like `ssh host -- cmd` (and commands depending on ssh
such as `git pull/push`) failed.

I can reproduce this:

```
$ ssh localhost
$ guix shell gnuplot
$ gnuplot
zsh: command not found: gnuplot
```

However (still within the ssh session)

```
$ guix shell gnuplot -- gnuplot
[gnuplot opens as expected]
```

and weirdly enough

```
$ guix shell --check gnuplot
guix shell: checking the environment variables visible from shell '/gnu/store/i4rj0banq044423if5xwb3df723g14r9-zsh-5.9/bin/zsh'...
guix shell: All is good!  The shell gets correct environment variables.
$ gnuplot
zsh: command not found: gnuplot
```

I don't really know what is happening here. Why does it work when
running the command directly and why does `guix shell --check` claim
that everything is correct when clearly something is wrong? If I
understand correctly `.zshenv` should be sourced in all these cases but
for some reason the problems only occur in some of them.

Any ideas?
