I think back before the C++ 11 STL the question of usefulness was
more important than now as Boost becomes more heterogeneous. I note
how many reviewers of Metaparse said they are not experts in that
field, or would even expect to use Metaparse any time soon
It's like with Edward's VMD library. I still cannot see the point of
it. But others said it was useful to their niche cases, and VMD was
clearly well designed, well tested, well polished and would be well
maintained with Edward as maintainer. So I felt it was a good
addition to Boost despite me personally not getting its point.
In other words, I think we're moving from an era of "many need this
so we'll build it" into an era of "I think this is cool, so I'll
build it and if one or two other people come to use it then great".
If I am right on that, it has profound consequences on what Boost is
and how it works going into the future, especially as there is little
incentive to buy into individual ivory towers from a user's
perspective if that tower is locked into its maintainer.
