Not much, I'm afraid.  A common reaction will still be "I tried to
bootstrap Bison and it didn't work.  This software must be poorly
maintained; I think I'll volunteer to work on something else."

And the problem with that is....?

How about another idea: have a very simple bootstrap script.  All it
does is fetch gnulib, and execute gnulib's more-complicated script.
We could call our new script "boot", say.  If this idea works, we
could copy "boot" to gnulib as well, so that other projects can use
the same idea.  The "boot" script should rarely need to change, and
the problems of it being out of date should be so rare that projects
don't need to worry so much about keeping it up to date.
