-----------------------------------------------------------------
Another way to state the above is to get with a Get the exact set of cells as
would be affected by a Delete _and no more_, specified by all possible forms of
a Delete op, we are missing Get#addColumn and Get#addFamily methods that take a
timestamp like Delete#deleteColumn and Delete#deleteFamily, but what we really
want is a timerange not a timestamp.

> Storing values with timestamps in the future is probably bad practice and can
> lead to surprises. If cells with timestamps in the future have ACLs,
> permissions from those ACLs will incorrectly be considered for authorizing
> the pending mutation. For sure that will be surprising.
> We should be able to avoid this case by resolving LATEST_TIMESTAMP to the
> current server time when creating the internal scanner for finding ACLs in
> the covered cell set.
> Documenting a todo item from a discussion between [~anoop.hbase] and myself.
