Have spent a good portion of my time on such strips, firstly snow if cleared right after its on the ground will give you a dry surface with good friction below about minus ten , the crap about "we cant scrape it at these temps" is just a load of crap, normally used by the airport operator to save money. If you are flying a 727 or anything Russian you can put the reversers in the first class washroom and you will have no problems with injesting sand, if its any of the Air Bus products one needs to be carefull, get the engine anti ice of before touchdown or you will have way too much idle thrust {what a stupid set up this is in our climate} also idle below sixty knots, start the APU before landing so if you do have to shut them down to stop sliding at least one is not left sitting in a dark cold aircraft. We have flown 727/737 / Airbus from sea ice, packed snow and all in between, its no big deal, just get it low and slow over the fence {or snow bank!} no auto land or auto throttle, plonk it on, lots of reverse to kill the top end speed, lots of auto or man brakes , if it cocks of runway heading a bit just let it slide that way, if you kick it straight in a cross wind you may finish of the side, taxi without engine anti ice if able on any Bus product, park it, enjoy the view and the fresh air!
