[optional.observe/4,8,12,14], these "Remarks" paragraph saying "this functions shall be constexpr functions", but they already declared as constexpr functions. Are these paragraphs redundant?

They're not redundant, because they're trying to say "this function shall be usable in a constant expression" but they're phrased incorrectly. Removing them would be wrong though.
