CMS Upgrade - Dump Older Logs and Stats

Can future CMS upgrades be made to have an option to purge logs and stats for anything older than 30 days, or perhaps an option to truncate the tables? Also would be nice if it would tell you the size of those two tables before trying to do the upgrade.

We had 58 Million stats entries on 1.7.6. When trying to upgrade to 1.7.7, of course it timed out. Simple enough to truncate the stats and log tables and rerun the upgrade, but still would be useful to have the option.
