I don't think it's out of scope.  If you're handing your scripts over
to the tender mercies of the BusyBox build process you should expect
stuff to happen to them.

Letting authors indulge their literary aspirations without bloating the
binary seems a nice feature to have.

I suspect that most authors won't care.  Those who do need their scripts
to be untouched should just ensure the first line doesn't match either
of the regular expressions.  The old csh hack of putting ': /bin/sh'
on the first line would do, for example.  And has a nice retro feel.
