Had this conversation before and I think we agreed to keep ? as a 
convenient shorthand even if help is preferred so it should not be 
deprecated but you can keep it from appearing in docs to advertise help as 
the preferred option. (\? is still shorter to type than help if you're 
worried about shell expansion which is rarely a problem in practice)
