Given that Boost.Container has a small_vector now, would a piece of work
that changed flat_set and flat_map to use small_vector<0> internally be
feasible? I ask because I feel like if this was the case it would be almost
trivial to expose flat_tree<N> through small_flat_set<N> and
small_flat_map<N> types to provide the small size optimisation for these
two containers.
