Crosswind pre-set aileron

Some years ago a B737 FCTM recommended the control wheel should be preset (vague guess of about yea!) into the crosswind at the start of the take off roll. This reflected a long accepted technique used for crosswind take offs for many types from light aircraft to heavies. Later this recommendation was deleted from the FCTM. That seemed logical because why preset the control wheel when the aircraft is stationary especially as it was just a guess at the right position.

I would have thought that the control wheel should only be turned into wind on a crosswind take off if you sense the into wing is rising slightly and you want to ensure both main wheels are firmly in contact with the runway. In other words leave the wheel central during the take off roll until it is essential for control purposes. This minimises spoiler drag at high speeds. Any thoughts on this?
