It depends on how much time you have. If you can always rely on having enough registered sprites, then yeah I guess so. Though I have to say I hate the idea. Personally I think having sprites do stuff for you is lame, unrelated to their usefulness.
If you can't always have enough services though, then having to summon them constantly can be too much fading, I'd feel. Especially since they start to accumulate OS immediately when unbound, and being converged upon leads back to you.
I wouldn't be surprised though if you can just always keep all your sprites at super high services owed so you never have to worry about it, though.... (also lame)
