It is actually already dynamically allocated (the private context is), but
I suppose you meant individual allocs for each dimension. It really is an
open question. Maybe it's not an issue, it's just that I would just think
twice before doing such change because I would assume it would impact
performance on low-end machines due to more sparse memory accesses.
