There is no profound reason, it was just omitted in favour of
other fields when cachedump was written as a quick debugging tool.

Note that stats cachedump is not recommended for use without a sane
limit on number of items to display. If you don't give a limit, it
will not necessarily display all the items anyhow, but will limit
itself to an output buffer of 2Mb. You can't reliably use
stats cachedump to print out information about *all* the items
memcached's holding.

That's one of the parameters you get in 'stats', isn't it? 'STAT bytes'
is the total number of bytes used by currently stored items.
