I'm sorry, but I just don't think anything like this is going to work.
Among other things, I think it will be a huge pain for existing library
authors (suppose I want to _add_ something to a test?) and will deter
people from contributing to Boost, and I don't think you're going to get
a positive consensus on it among existing contributors. This seems like
an overreaction to one person's failure at disciplined management of
Rather than set up systems that will decrease agility, increase
coupling, and give contriutors the sense that the Boost community
doesn't trust them to do what's right, suppose we set up a mailing list
to which all the test checkins are posted? Then anyone who wants to
monitor the evolution of a library's tests can subscribe to that list.
