It's no longer simple and straight-forward
but I don't think it's too tricky either.

It must depend on the specific tyre, the upper reaches of the actual ambient temperature range, the choice of vehicle, and probably most importantly, the style of driving.
I have no doubt that people with an excessively pressing-on style will find winter tyres in the height of summer to be quite lacking compared with what they expect and want.
This would be exacerbated if the winter tyres are narrower and higher profile, mounted on smaller wheels, compared to the summer rubber. Narrower tread appears to trade increased peak accelerating and braking capability for reduced peak cornering grip, which seems a sensible choice for slippery conditions but less so otherwise. Greater sidewall height leads to a more compliant ride but probably lessens steering sharpness.
For normal people in normal circumstances winter tyres are probably fine throughout the year, since the risks of not having maximal grip in good conditions are much less than not having the necessary grip in slippery winter conditions.
As I've said repeatedly, though, I think all-season tyres are a better choice in most circumstances. Certainly I've not found serious downsides in the height of summer with Vredestein Quatrac 3 tyres in both 165/70R13 and 195/55R15 sizes.
I have trouble understanding why some drivers who appear to eschew any kind of pressing-on style would not choose to use all-season or winter tyres throughout the year, unless their cars have large wheels with ultra-low profile tyres.
there is only the road, nothing but the road ...
