When does a particular swing cue or thought become unnecessary, or possibly detrimental? For example, if one is TRYING to do something they are ALREADY doing... they may not need to think about or monitor that particular thing.

Once you learn how to dance, type, play an instrument, etc.... you don't have to think about it much, or at all. Learning golf swing mechanics should be similar.

True.

Yet, the problem is to deal with the situation affecting the execution of the swing mechanics. It's like dancing in front of different crows on different stages, typing with different typewriters, playing an instrument indoor or out on the street.......

There is rarely identical playing condition among golf shots. I found the best way to deal with it is to "execute like a machine", which does only what the "program/intention" (after "thinking as a golfer") says.
