Reserving a jumpseat would be nice, but I don't know if I like the idea of a "fastest finger" contest either.
DAL has basically the same thing but it's not just for to/from work that makes it nice. As someone who has worked/commuted/traveled at companies that do both, I can tell you that being able to reserve the JS is infinitely better for both junior and senior.
