Good points & I agree.
I use a nail between the sheathing for spacing & it has worked fine for the many many roofs I have built. IMO you do need a space for expansion.
If the customer wants H clips than I would put them in (waste of money).
If you need H clips than IMO something is wrong with the rafter spacing or quality of the sheathing.
