It is part of POSIX:

The problem is not with env, but with shebang lines. I believe that

  #! program argument

works on most systems but using more arguments only works on some of
them. Therefore, even without env, you wouldn't be able to call perl in
a shebang line with more arguments than -w in a portable way.
