Playing Devil's Advocate for a moment:
With an end-user hat on, who will only ever download the tar-ball of the
latest release, how precisely does the internal infrastructure affect
me, and why does it merit a change to the end-user visible version number?

The only people who are really interested in the Boost version number
are the people who download the tar-ball. Developers are using git and
know all about the change. They don't need a version number to tell them.

I still think that the most sensible reason for moving to v2 would be to
indicate that C++11 support is expected. v1.x could be used for
maintenance releases for pre-C++11 compilers. A library may appear
identically in both the v1.x and v2.x releases, or it may have split
into two release branches, at the decision of the maintainer. This would
allow maintainers to move to supporting just C++11 for new work whilst
leaving the pre-C++11 library available in the v1.x release series.

Testing overheads wouldn't be significantly different: each compiler
configuration would be either v1.x or v2.x: compilers with switchable
C++ version behaviours would need multiple configurations - but they do
now, anyway.

v3.x would be for C++1y. (If there are sufficient differences to justify

Biggest hassle (and I don't underestimate the effort involved in this)
is the release process.

Just my thoughts as a long-term lurker,
