Classically, this is when a large-sized BOF conference might form an “editors” committee, delegate the entire topic to it, and ask the committee to elect one presentation each day that the committee feels would be valued by the conference as a whole. It maintains the enthusiasm for those who truly value discussing that subtopic in detail, and it’s an effective tool for keeping evangelism and/or holy wars within a given group sect from sucking all the air out of the room for everyone else. (Modernily, subreddits are an expression of that exact same model, and remarkably effective at scale for that purpose.)

You could say it's more akin to if we have all been writing in a assembly and suddenly we got access to compilers and high level languages. Would we all be complaining that every conference is "about compilers"?
