R6RS *is* a Scheme standard and the only one saying something about
the general #!<identifier> syntax.

My point here is mainly that we shouldn't have to reinvent the wheel
when it is already invented.  We should only reinvent obviously broken
wheels.

R6RS *is* practical for modern, portable Scheme code.  It was designed
as such.  Some will disagree, but then the current R7RS is even less
practical.

I don't see why it is necessary to postpone this (possibly after the
last SRFI will have been written).  A hypothetical flag #!srfi-243
will certainly not be used by any other SRFI.
