One thing I'd like to see is a cmd argument as well, to allow for
example allocation vs. reservation (i.e. allocating blocks vs. simply
reserving a number), as well as the inverse of those functions
(un-reservation, de-allocation)?

If the allocation interface allows allocation/reservation within
arbitrary ranges, if the only way to un-allocate is via a truncate,
that's pretty asymmetric.
