Yeah, really. If it's a hand vertex, it would be subject to the base bone, all of the spine bones, the shoulder bone, the upper arm, the lower arm and the hand. That would be a nightmare to calculate.
If you only need a few of them, I would definitely just create them as additional bones. Bones are just pivots anyway really, and putting them in place when you're rigging the character is probably easier than doing it in code.
Still until _PC explains what he needs it for, it's hard to pick the best option.
