I can answer my own question too, actually:
I've (finally) learnt that wet falling snow is, and should be, a showstopper. Bikes do not work well when packed with wet snow, bike riders do not function well when cold and wet, traffic is dangerous. Extreme cold (defined as anything I don't already have gear for
) is fun to ride in, a little scary if you have to stop, but usually dry and fairly easy as such, even though you spend a lot of time in just 2 or 3 gears. Heavy rain I don't like, the bike works fine but needs maintenance afterwards. Passable, just not much fun.
What shouldn't be a showstopper around here is (fallen) snow. Even though the snowplows take days, weeks or months sometimes to do my local roads properly, the bike path 300 yards away is more often than not freshly plowed. So even if I may have to carry my bike down there, it's good sailing from there on. Finding good bike routes is crucial to a good winter commute, though, the neato little shortcuts I use in summer can be inaccessible and some of the regular roads can be dangerously narrow.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
