Would it be feasible to add a Pause Queue feature?

[Risvertasashi]

Ignoring the obvious limitations that can be placed on any such system, such as as maximum duration before the pause is broken, making that impossible, how is 72 people in line in front of you different than 72 people in line in line in front of you (where 15 of them just came back from a pause, long or otherwise)?

At worst, it amount to more people in the queue because more people won't have been ejected from it. That higher population of users is something we usually want, because it generally reduces queue times for all but the most inflated role(s).

It would be different because people can actively cut in front of your position in the line. It's not really 72 people in front. It 57 people in front of you... then 15 people unpause, so now it's 72 in front. Then it goes down to 57 again... 15 more people unpause, and it's back to 72 again.

See the problem? This probably wouldn't happen offpeak, but on peak, especially during the ramp up hours, it very much could happen.
