I've always believed the reason some manuals say to engage at WOT is to make things a little simpler for some people that might not know how to use just enough RPMs to not kill the motor. People that would possible think something was wrong with the mower and maybe carry it back because they couldn't engage the deck at idle.
It's definitely less abrasive on the clutch to engage or disengage the deck at the lowest possible engine speed.
I still prefer a manual PTO. Although, I've read somewhere about there being an elec PTO that they refer to as (I think) "soft engage" or something to that affect. I imagine that it engages more slowly, resulting in less wear on the clutch.
Everyone has their own opinion and reasons for having that opinion. I can understand that there is a safety benefit in the elec PTO by shutting the blades down faster in the disengage process.
