Slight correction: all passengers checking in a bag need to be present, which is not exactly the same thing. And if one person has enough allowance to cover all the bags (e.g. a couple travelling in Club with one bag each but a 2x2 allowance) then only that person needs to be present as long as they’re happy to put them all under one name.
