To some extent Skoda are already doing it. There’s a store from which you can buy software based features from packs you didn’t buy on purchase. Things like the ACC, auto headlight main beam all available at an extra cost (assuming hardware allows) through your infotainment system.
I vaguely remember an article where BMW were talking about a monthly subscription for software controlled options, so you buy a car with the physical capability of everything (nearly) the top of the range model has but all these features switched off, then for a monthly cost, you can buy what you feel you need.

I'll try to give my honest opinion but am always open to learning.
