ask a tuner why they fit them then, ive got a -31 actuator on my stage 3 turbo but the bleed valve was still fitted by jamie at jamsport, i think its fair to say jamie knows a little more about rs turbos than most of us, no ????.

as stated before, bleed valves are fine if fitted by someone who knows whats theyre doing and then left alone.

if worried i think some people fit some locking wire so they cant be adjusted or come loose on their own.
