Captain Mongo your outfit seems like a pain in the @ss. xD
Again I don’t see a big issue of using managed speed and configuring. That’s pretty standard. IMHO, the annoying bit with this is the thrust variation and risk of flaps overspeed when in bumpy conditions and heavy weight. Also the engines will keep spooling up and down during deceleration when configuring unless you are high on profile. I like to have the engines on idle all the way and ask for flaps when the speed is 10 kt below vfe. So to avoid thrust variations I will often select speed Below Green dot and S speed to configure accordingly for a smoother and more efficient transition to VAPP.
