Well said. We are having a similar "fight" where I work now. Way too much premature optimization. I think the one concept that takes a while to really understand is to focus on separation of concerns. It is far too easy to get encapsulation wrong. People (imo) generally forget to apply the SoC test that tells them where to draw the line. We also have a lot of parallel development where re-factoring a View (Screen) could cause a rippling failure to other people's code. Too often they try to reuse everything instead of the important part of extracting the shared business logic into a XXManager and letting the Views just be dumb. Who cares if two Views developed in parallel might be too similar? It might change in the future and don't have to worry about 1 View doing 2 jobs.
