Crossover tyres really don't seem worth it as they are only marginally better than summer and the gap to how much better winter tyres are is still huge.
You've obviously never read/seen the reviews of the newest summer-biased winter tyres then! Watch out for some all-seasons though as they can be a bit crap in the hot/dry conditions (relatively of course).

There's Michelin CrossClimate+, Continental AllSeasonContact, and Goodyear Vector4Seasons, and they all work well in snow, and have the 'mountain' symbol on as they've passed the relevant tests and are legal to use in any European country where they are mandated!
Obviously they're not as good as a full winter tyre, but they have other features which make them perfect for the UK seasons (e.g. better wet performance than most winters, better dry performance than ALL winters, better wear rates than most winters, lower road noise than most winters, don't have to have a 2nd set of wheels or faff around with swapping them over twice a year).
Everyone will have a different set of circumstances they need the car/tyre for.
I've got CrossClimates on the Alfa (as the Z4MC has been retired from daily duties after 150,000 miles) - and that does 25,000+ miles a year of B-road blasts (ask some of the National meet attendees on here to see if they thought the Alfa had a lack of grip in either hot summer or wet summer driving), early/late season Ring trips (including 20 laps), and survived happily through the 'Beast from the East'.
I couldn't do that on just a set of summers or a set of winters - I'd have to have both - and in the case of the off-season Ring trips/track days or dry/warm winter days, I'd have to carry both sets (not easy in a Z4MC) - so the summer-biased winters are perfect for me.
In 30 years, I've never been stuck in winter in any car on summer tyres (including my Corrado VR6, Polo G40, BMW M5). I've also never left the house in the Z4 when there's been 4 inches of snow on the ground.
Here's the car in Wales on 2nd Jan 2009 (a month after I bought it) - on 19" Pilot Sport 2:
Here's the car a couple of months later (on the same tyres) when I drove the 60 miles to the supplying dealer to get my service book stamped with a missing service (just before they closed when half their local staff couldn't make it in):
