You're missing the point - ramps are a shortcut.  If a receiver is going to
disregard the ramp (and use it as a point value instead) then the sender may
choose to not send a ramp at all, and instead use the more expensive but
more accurate series of point values.  Without that info, the sender might
send a ramp to an unramped control, which would be worse than having no
ramps at all.
