That's a good argument.  I was unclear on whether there would be
choices, and whether there were some platforms that needed particular
other shells, since presumably we're talking about platforms whose
/bin/sh is too junky to start with, so they are in general troubled.

So it sounds like you are suggesting:

  commit the ability to use dash now

  (some point later, after the freeze???)  remove pdksh as a bootstrap
  shell option, resulting in the --enable-dash option going away,
  because it will just be used on platforms where pkgsrc knows that
  /bin/sh is not ok?

Or am I still not following?
