Right now this isn't an issue.  I specify the path of the ruby file I  
want to run and it Just Works.  Using env will make it an issue.

I think the issue is when someone installs a gem and wants to run
a ruby executable from that gem under different versions of Ruby.
Hard pathing in the shebang will not work in this case. The only alternative
is to use env.

Along with that decision, another problem arises. And that is with
options that authors add to the shebang. The problem here is that
not all OS's support options with an env shebang.

My opinion is that there are too many scenarios to cover here and
that the best solution is to provide options to gem that let people
control both the shebang path and the options to the shebang.

I'd rather have the default be the current behavior so things don't  
mysteriously fail when I upgrade a gem.

I think that has already been stated. The default won't change,
that is why I suggested a couple of option flags.
