This is what I'm talking about. Design by the standards committee is
not a good use of the committees time and resources. If they insist on
mandating libraries (itself a bad idea), the should just stick to
evaluation of existing libraries.

LOL - Right. This is what all organizations do when they are faced with
the failure to accomplish their stated objectives. They add more
objectives! The try to become too big to fail. Sears heads down the
toilet and they ... buy Lands End. It's an all two familiar patter.
What they need to do is cut scope back to something they can actually do
a good job on.

So he couldn't meet the requirements of Boost so it went to the
standard. Boost standards exceed those imposed by the committee! This
is why Boost is more successful than the committee in promoting
development of quality libraries.

I've had a lot to say about documentation. My advice to you and others
with this complaint is that you must be doing it wrong. If you're
waiting until the end of the process to add documentation, you're
missing out on getting a better design. Here is what I have to say on
the subject: https://www.youtube.com/watch?v=YxmdCxX9dMk Just follow
these instructions and you'll find documentation a joy to write and the
quality of your libraries will be much improved. You'll also find the
review process, be it at C++ committee or at Boost, much, much less
onerous - almost a pleasure. And you'll find that the review itself will
be much, much more helpful than you've found in the past.

Hmmm - I'm not seeing how spending more money would change peoples way

It would be free and alot easier if people just spent a little time
learning how to do it properly.

Hmm - once a library is standardized, I believe that vendors are
required to provide it so that their compiler is considered
"conforming". BTW - how a compile with easily demonstrable bugs are now
considered "conforming" is beyond me.

Personally, I've got no problem with "too niche" libraries. You're
right they might have to scrounge around for a review manager. But as
you note this is not a big problem.

If Boost were able to support modular deployment, this problem would go
away. That is, if a library weren't being used, no one would download
it and it wouldn't matter.
