[rules-users] Agenda-group in fact insert time

Hi, I just noticed that even I have different agenda-groups, all groups are evaluated during fact inset time. In an extreme case, if I have 1000 rules in agenda-group "A", and 1 rule in agenda-group "B" even though I just want to fire the 1 rule in agenda-group "B" by adding AgendaFilter in fireAllRules() all those 1000 rules in agenda-group "A" will be evaluated (i.e. methods in the "when" part are being called) even worst if I have complex logic in the "when" part for these 1000 rules, e.g. accumulate/from, not to mention eval Isn't that quite a performance impact? And forcing people to put their logic/checking/matching in the "then" part? How would you justify this? Or is there something I've missed that you can actually evaluate the rule in agenda-group "B" ONLY, when fact is being inserted?
