Subject: [boost] [Containers] Should flat_* expose implementation vector?

Dear All,
Should Ion's proposed flat_set, flat_map etc. expose the underlying
vector that they use as their implementation?
Pros: it lets the user efficiently load and save the content, and
implement algorithms that cannot be done via the flat_* interface.
Cons: it lets the user break the invariants.
Const access to the impl is another possibility.
Related to that: could the implementation type be a template
parameter? Example: could one implement a flat_set on top of a
stable_vector? (Is that useful?) And/or: should flat_* actually be
adaptors that take a reference to their underlying implementation?
Regards, Phil.
