Enacting proposals in order is a bit of an anachronism when we have the tracking bar to the right. In practical terms it does very little to slow the game down, as the enactment of proposals is more often a function of when admins actually turn their attention to those proposals rather than a function of the rate at which they reach quorum.

This does have several advantages, though - it means that players no longer have to have their votes dictated by the impulse to expedite the processing of the queue, it means that controversial proposals can be lingered over while less important (or more clear-cut) proposals can continue to be processed, and it means that urgent problems can be fixed urgently.

It is, of course, possible to create contingency loops, where two proposals are contingent upon each other and thus neither can be passed; but it has to be done deliberately on both sides, so can’t be done as a hostile move, and both will time out naturally and be failed, so I don’t see it as a huge problem.
