It's un-fortunately a sad state of affairs. What bugs me the most is
(nobody here to blame), that there are (on this list) on a regular basis so
many people stating they would like to "contribute" to Boost... and then,
there's silence.

No proof intended, just examples... For some reason, lack of maintainers,
backward (binary) compatibility, things don't progress... And one ends up,
like you suggested below, doing ones' own thing.

Reason number one is simple, it's this rule: "Thou shall not inherit from
class xxx publicly in the absence of a virtual destructor as it effectively
prevents you from polymorphic use of descendants.", and this rule is
repeated over and over again. boost::pool does not have a virtual
destructor (trivial change, I agree, but that was what I was doing in the
first place!).

Getting back on the thread we are actually discussing, it seems to me that
there is a discrepancy between what Benedek proposes and how this library
is being reviewed (by some), that's the source of the subjectiveness you
are referring to, IMO. The idea (the way I see it) is not necessarilly that
the library will/or should be minimal and do the right thing all the time,
but that it should provide maximum control and potentially (when well used)
optimal performance. We are looking at control C-style. Yes, one can "shoot
ones' leg of". For me, that's understood from the outset. It's most
probably not a candidate for standardization, but, on the other hand, might
become quite popular with game- or HFT-app-developpers.
