Could a "universal exposure" setting be practically possible?


Not sure how uneducated this question is, but I'm interested in learning, so thanks in advance for your indulgence.


Film physically changes over the period of time it's exposed. A digital sensor, though, doesn't; it's just reading data. Is there any reason the camera couldn't be made to "remember" what the sensor readings were at every exposure point? It's just data. It might be a lot of data, but there are times one might want to do that, no? Giving far more flexibility in post processing.


If data storage were not an issue, is there any reason this couldn't be the norm, at least for professional and art photography?
