I feel the extra waffle was introduced with no intention of increasing safety, more so to apply legal standing to the instruction. "Climb via Sid" "Line up and wait" "Hold short of Runway XX". All tell you what you already should know, however now that it's reiterated several times as well on the radio you can't say you did not understand what is a rule anyway. The rules state that I have to comply with all of SID procedure when cleared via one, why do I need to be told again to comply with the altitudes, I know a line up instruction is not a clearance to taxi or take-off on the runway, so why do I need to be told to wait, I know I can not enter a runway without a clearance, so why do I need to be told to hold short of one until instructed so... The reason, so they can listen to the tapes and conform that you acknowledged your legal responsibility, not one drop of safety in it. These extras are just as bad as the "pending clearance" brigade and guard Nazis.
