How much would it be difficult, in your opinion, to allow users to
provide third-party accessors?

My impression is that "proper support for nested data" is way beyond
the amount of complexity that we want introduce in the code base, but
that with EA we should be very close to allowing them to do it
themselves.

(Not commenting on the other points because I don't know enough about
what was discussed, e.g. on the block manager rewrite)
