I'm not trying to contradict any good intentions to put some reasonable limits but imo you can only require "2) Full-time role availability" and all that "sick", "holidays" etc corporation-like limits when you start to pay corporation-like salary and not only "token of appreciation for open source project volunteering" as it is now. Until then we should apply "full-time" requirement proportionally to that "token" to get someone seriously working for us imo. Being member of Core Team doesn't magically solve simple real world needs. Side note: actually, this "title" doesn't give any additional benefits (as one might think) - it only brings additional limitations (rules like these), more responsibility (managing all these accounts with admin/moderator access to several critical resources like forum or github or media) and sometimes even another vector of personal attack ("Ah, Evil Core member!") Rules 1, 3, 4 make sense imo.
