Do you even ready what I am writing? You are asking for them to use outdated file systems because that is how it was back then? That makes no sense! The whole reason why they are even able to do Classic servers is because they (or someone from outside the company) found a way to add Classic into their existing infrastructure. Re-implementing old and outdated systems for the sake of nostalgia, something which has no effect on gameplay itself, makes no sense, and neither does it for those who are still running 1998 hardware or Windows XP because they are a small fringe minority.
