I think this is not needed. I wouldn’t change it.

The only reason to use the #!/usr/bin/env xxx thing is portability. 
But this script is not intended to be portable. It’s for macOS.

There are possible drawbacks to use the #!/usr/bin/env xxx thing.
The least one is the indirection José already mentioned.
The next one is the inability to say which bash will be executed.
If $HOME/bin is in PATH and the is some executable named bash it
is started by the env utility. Do you like that?

Eberhard, why do you see any real benefit here?
