If you're doing any kind of serious work, the time investment per library
will dwarf the effort of filing a ticket and sending an e-mail. For it not
to do so, the work needs to be either superficial or heavily automated. Even
then, to be sure that the massive changes haven't broken anything, you'd
need to run the entire test suite after each round of changes. This wouldn't
be any fun, either.
It doesn't even matter. The process is not as inflexible as you think.
Filing a ticket and notifying the maintainer is a matter of courtesy and
respect, it's not a requirement. If you're good enough so that your changes
are entirely beneficial, nobody will object.
But that doesn't matter, either. The process is emergent from the structure
of Boost in which maintainers are responsible for their libraries. This
means that if your massive changes introduce bugs in some library, it will
be the maintainer of that library who will have to deal with the bug
reports. This naturally tends to make (active) maintainers somewhat
This all works fairly well in practice, if your measure working by the
actual results. Stephen Kelly's situation is unique and one-off, because of
the impending transition to Git. Normally, we'd do things in our
old-fashioned, non-energetic, inflexible way across a few releases without
entering the news.
