And the reason is simple:
I want to be as explicit as possible and allow the reader of my code to have an uninterrupted flow.
Think about it. Every time you encounter the it keyword you do, a quick, conversion between what you see and what it represents. Personally I do it even in very small lambdas, imagine if you are two or three lines deep in a lambda and you see an it:
It might not look much in this simple example but read it now with an explicit value:

Your last example, you could shorten to
