That was the reason for Boost in the first place, so definitely!

These lead to so many things, not unlike the benefits from space exploration: pens that write upside down! Seriously, such work has led to lambdas, improved TMP support, etc.

By virtue of Boost's reputation, libraries in Boost gain wide exposure. Therefore, the coding practices exhibited by those libraries tend to become commonplace. That doesn't mean that efforts within Boost should be advanced to make Boost a better vehicle for those things, but rather that, because Boost is such a vehicle, the effects of things done in Boost must be considered.

That, to my mind, fits within b).

There may be a few additional items to list, but it is definitely not open ended.

I can go along with that to a point. Anything accepted into Boost must meet the usefulness criteria. If too few find a library useful, it should not be in Boost. That helps to keep Boost manageable. Many burdens are multiplied by the number of libraries in Boost, so keeping that number small is one of many forces to balance when considering whether a library should be accepted.
