It was the reason Boost was founded, but once C++ standard absorbed most
of Boost foundational libraries, Boost needed a new purpose. There was
much discussion of this around 2010ish but there wasn't much consensus,
and we just continued without really thinking about it.

The only reason boost was successful, and continues to be is that it's
one of the few places where one can acquire quality quality C++
libraries including code, tests, documentation, rationale, etc. Vendor
supplied C++ standard libraries also fulfill this role. But the C++
standard can't evolve fast enough and vendors couldn't keep up in any
case. Hence the need for Boost.

That Boost must supply high quality software, and only such software,
has been a fundamental premise of Boost since it's inception. The
decision was made long ago. Of course the community could decide that
quality could be de-emphasized in order to promote some other value(s)
and that would be a decision for the community to make. But so far I
don't recall anyone proposing that.

Hmmm - I don't understand what that means. Is C++ library development
going somewhere?

Hmmm - what does experimental mean in this context? If means that
quality has been compromised to get the job finished, we shouldn't do
it. If means some software which no one would ever think of putting
into the standard (symbolic differentiation?), I wouldn't have any
problem with it at all. If someone want's to strike out with a whole
new direction for character encoding, I would OK with that. But what I
would not be happy with is an incomplete/buggy/low quality of any of
these things.
People use boost because:
a) it's documented
b) it works
c) it has passed a review process which certifies the above
The above saves user time - which the fundamental thing that they care
about.

How would Boost changing it's mission address this problem?

Note that the Boost Library Incubator (www.blincubator.com) was
conceived to fulfill a role similar to that which you describe. The
requirements to be accepted into the incubator are objective and require
not subject review. The web site could/should be simplified/updated as
much of the functionality is now better implemented within github
itself. But in principle it seems similar to what you have in mind.

All true, but it should be good enough to pass a boost review before the
committee decides to consider it.

PS: Off topic
TL;DR
The role, goals, methods, of the C++ library committee have been the
subject of much discussion of late. To many of us, it seems very clear
that the process is not scaling and the committee as it currently
operates can't keep up while still maintaining the level of quality that
we and other users demand. Something is going to have to change here,
but of course we can never agree.
