The obvious question one might have is, in what scenarios is a database that
only supports insertions, but not updates or deletions, useful?

A follow-up to that is, is it not possible to add update/delete support to
NuDB by just appending the new data and making the key file point to the new
location (using zero-sized data for deletions)?

Last, the README says "Value sizes from 1 to 2^32 bytes (4GB)", but the file
format says uint48_t. Which is it? 2^32 is perhaps a bit limiting nowadays.
