Yes this is still on the cards for inclusion.
Thanks for summarizing the links.

RMS has stated in a previous thread that CC0 code is compat with the GPL,
and that we don't need copyright assignment for copies of external libs.
With that in mind we'll look at adding b2 possibly to gnulib,
but available in coreutils in any case.

thanks,
Pádraig.
