While I can understand the need to reduce quorum to facilitates operations and technical upgrades, would it be possible start establishing a criteria for either increasing the quorum again in the future? Or even then, what could justify lowering it again in the future?
Besides that, does the proposal account for the role that abstain votes play in these scenarios? I believe this issue was raised by @cupojoseph here and though their idea was initially prompted by a non-constitutional proposal passing, these are two topics that are tightly connected nonetheless.
