For me this part of the logic (contrary to the "mate >solving logic".

You could also say: Mate or not mate say to you practically everything about the position. Problem is only that number of plies that you can search is limited but if you search deep enough you can decide if the position is a draw(no possible mate) or a win for one side. I do not think that it is correct because practically you cannot search deep enough and for the same reason only material evaluation tells you practically almost nothing about the position(I agree that theoretically it can tell you everything but I am not going to live 10000000000000000000000 years to see it).
