I'm waiting for the torrent of situations in which I cannot maintain positive buoyancy at the surface. So far, there have been.....two.....rare circumstances. Since I'll be in a drysuit well before 1000 dives when my corregated hose will invariably rupture, causing me to die, I'm not too worried about that. Even diving wet, my rig is at worst 2lbs negative. I'll be able to kick at the surface that EASY. Debris in my power inflator? I don't set my junk down in sand.
Don't tell me I need ditchable weight on my drysuit configuration. That is ridiculous. How many failures are you going to plan for?
