Yes, such spatial-based clusters could help. It can work well for operations of relatively large scale (ex: bulge this part, delete that part), however it won't be good enough to keep track of micro operations (collapse that edge, crease that vertex...), which is the way most people model, and it would create an important performance overhead. Still, I agree it can be quite useful for type of some work such as rigging templates (it kind of falls in the GATOR land).

[g] Feels like more of a limit than a permit. Instead of static clusters of fixed component collections that XSIs ops seem to use, Flexible component collection methods, like by bounding volume etc I think would allow many ops to remain functional with changes made.

Actually, to avoid problems, you should actually create all the clusters that will be used in your animation stack (ex: to be connected to a deform) while you have the slice disabled, same for the polygon cluster used for hair generation (if you have one). Otherwise, since the slice changes the indices of the components, the clusters created after the slice will change randomly.
