I think this question is ill-formed. It presumes that someone (us) can determine what other people are going to do. No one has the authority or influence to do that.
It's a question of there being a consensus, and if not, a sufficient critical mass. What I saw there before is the usual complaints as we've seen here for a decade now, the usual suggestions for solving it, and the usual lack of anybody actually doing anything. Which is just pointless noise. So I made that questionnaire to see who would publicly go on record with where they are currently at. There is obviously no consensus, though I note with excitement how many fewer naysayers to real change there are compared with even three years ago. So clearly things are shifting, and I note a number of people whose opinion has transformed radically from where they were only recently. That means that if somebody did roll together a tighter, smaller, more focused Boost 2.x distribution of the better quality libraries, it might have legs. Up to you Boost! Niall
