I know I'm a bit late in coming to this, but I should point out that
Number of Hosts is not the same type of measure as Number of Requests or
Number of Bytes. They are simply running totals or incremental counters,
and impose almost no memory overhead.

To calculate the "Number of Hosts", you have to keep a table of every
host that has occurred so far in the given time period, and check to see
if each host you encounter is already in the list, or is a new host.
Doing this for a single time period in a given report is one thing, but
doing it for multiple periods within a single report (daily totals in a
weekly report, or weekly totals in a monthly or annual report), would
impose a huge overhead. It's simply not worth adding all that
functionality to Analog, because it's fairly straightforward to just run
the weekly reports to get the counts you want, and then to use cached
output to generate the reports for the larger time periods.
