Of course I can't speak for the others, but it's my impression is that while
Bruno, Paul and Jim are fundamentally receptive to the idea of a re-engineered
bootstrap script, they (rightly) don't care to let me push to gnulib until all
2500 lines of the replacement have been peer reviewed.
The latest version can, however, be dropped directly into the override
directory, and will upgrade itself from changes to the override module sources:

21 gl/modules/inline-source
4978 total
The files all pass libtool's extensive shell syntax-check rules, are all
very well commented (which contributes to their relative large sizes) and
there's also extensive texinfo documentation, though I'd need to check
that it's still accurate after the recent round of changes where I split
my original submission into the several independently useful scripts
shown above.
We're overdue a new libtool release which I'll start work on in the New Year,
after which I'll try to lobby for the non-clashing, non-bootstrap files from
above to be accepted into gnulib given a little more time for adoption of
that release to improve confidence that those files (which are now deeply
integrated into not only libtool's bootstrap, but also the installed libtool,
libtoolize and ltmain.sh files) are portable and functional enough to warrant
inclusion -- since the release process will require libtool to compile and
pass extensive testsuite on the 30+ architectures I have access to.
As to whether the bootstrap module is adopted, I'm relatively happy to make
use of it in my own code and make people aware of it as an alternative if it
ooks like it might prove useful to them rather than hassling the gnulib folks
any further.
