While I sympathise with the sentiment, there are a number reasons, I won’t be doing this:

It introduces a degree of subjectivity, which is something, I’m trying to avoid.
It will lead to endless debates on how a scene should look, which is something, I’m trying to avoid.
If I manually adjust one shot, I will have to adjust all of them, which adds a ton of work (as it currently stands it’s already months of work), which is something, I’m trying to avoid.
Doing manual adjustments is not my forte.
