I think that, for some, the completion of any given crossword is not necessarily why they contribute to the site.
Quite often I cant get to the papershop so this site is a nice diversion which I enjoy. To have that enjoyment it is pointess telling me 19ac is "5/11" without a clue etc. a short while ago some of the regulars tried to introduce a protocol which meant that clues and letters be included to open the forum to all. Is that so bad?
