I don't understand this remark.  If the script shouldn't depend on
config.status, well, then why does it read it?  There should be no
additional limitation between reading the script and running it,
at least how I understand it.

Well, it would certainly be easier to fake
  echo @TOPLEVEL_CONFIGURE_ARGUMENTS@ | ./config.status --file=-

with a two-line script of the form:
  #! /bin/sh
  echo args...

than it is to fake internal details and remove the complex quoting
done inside config.status.

Fine with me, but not my area of expertise.
