In the past, it took two years to merge my first PAUSE on Plack branch into the master and three years to merge the next PAUSE on Mojolicious (actually, two years to deploy and another year to merge). Now the question was: how long would it take to merge the next big thing, multifactor authentication for PAUSE? Two years, three years, or maybe four years this time? I already had a two-year-old draft branch and initially wished to merge it this year. However, things went differently.
