It is possible, using `/usr/bin/env -S command arg1 arg2` , as of 
coreutils 8.30. I have been using it at work and it's working 
perfectly. This functionality was already supported by FreeBSD 
[1] for ~15 years, but the coreutils developers implemented it 
just ~3 years ago [2].

The main disadvantage is that it's obviously not very portable, 
e.g. all users/developers need to use a modern linux distro, but 
for some teams this requirement already there for other reasons, 
so it's not a problem.

Example:

This was extracted from a larger project, so it may not be useful 
on its own, but hopefully it should be enough to showcase the 
usage.
Also, if you can use rund [3], it's likely a much cleaner option.
