I'm already aware of this problem too. Unfortunately I don't have a good
measurement of 'how much interest is enough interest?'. I've browsed all
the (so called) searchable archives of boost.devel, but didn't find
anything useful. Either the search function was too limited or the
search results couldn't be ordered in threads or there was no 'view
complete thread'. So I have no clue, how many replies indicate enough
And of course you have to keep boost as small as possible. If it becomes
too big, nobody will use it anymore, because nobody have a complete
overview and is able say, what's actually available (and IMHO boost is
already too big, the fundamentals are coupled too tight with high-level
OTOH intrusive containers are a very fundamental piece of code. You can
build all sort of containers on top of it (including STL container,
boost::multi_index_container), while you can't do the opposite. But I
admit, that the application area is limited - they serve either as a
base or are used in perf-critical parts. And as you wrote in another
post, the application programmer rarely needs to write really fast code.
In addition, programmers coming to C++ from 'higher' languages (Java,
script lang.) will certainly have problems to understand the differences
  between intrusive and non-intrusive containers and hence don't
consider intrusive containers even at the right places.
Nevertheless IMHO intrusive containers belong to boost. They are part of
an development process opposite to the popular one (that is, they
reintroduce one of the roots of the language instead of trying to
emulate yet another JSDK/C# library feature). I wouldn't go as far as to
say they belong to std (as someone emailed me), but once in a while a
question in a newsgroup pops up, where intrusive containers either fits
perfectly or at least have to be considered as a possibility.
