If by the first point you mean "assume V1 when no info function is found",
I object to that. If you mean you want to require an info function, that
might be OK.
The habit of zero-initializing Datums has got exactly nothing to do with
V0 functions; it's about ensuring consistent results and avoiding
heisenbugs from use of uninitialized memory. I do not think we should
drop it.
