No, you are absolutely right.
A balanced rig may or may not include ditchable weight. The only time you *need ditchable weight or (redundant buoyancy) is when you are (purposely) diving unbalanced. That may include equipment you can ditch in an emergency, like a can light, scooter, camera equipment, etc.
The issue is likely because your XDeep AL bp weighs 6 lbs. Compare that with the Halcyon AL bp that is 2 lbs or the Steel bp that weighs 6 lbs or perhaps others.
That few lbs that you're overweighted isn't too bad. It should be quite manageable. If you can swim it up from depth without air in your wing when you're in your warm water wear, you should be fine.
You're also right that you don't add buoyant things to yourself in order to require more weight.
Do you have much gas in the wing at your last stop or at 10 feet? Ideally, you want the wing to be empty at 10 feet and still be able to hold the stop and make a controlled ascent.
If you're correctly weighted, the worst you will be at the surface at the beginning of the dive, is neutral. At the end of a dive with a mostly depleted tank, you would be a little positively buoyant, even if your wing didn't hold air. That's exactly what we want.
With some of the advice on having ditchable weight at all cost, you would think that those of us who dive a balanced rig are plummeting uncontrollably to the bottom when we jump in at the start of a dive. Um, nope.
Hope that helps...
