I would say using env in the shebang line is useful. Particularly for
portability. As a developer, I wouldn't like removing it from my programs.
Moreover, if your PATH is compromised, you're most likely screwed.
I understand, that env use in scripts makes is inconvenient in some cases,
but I think that RPM build procedure and Fedora practices need to be fixed
instead.
The number of packages using env in scripts alone shows that it is a
widespread and useful practice.
