This will be very good at fretting if the refurbisher swapped out RAM or mass storage; but it's not like onboard diagnostics are all that good at picking up the difference between a machine that has had a fairly hard life and now has somewhat dodgy ports and a bit of uncomfortable flex vs. one that sat on a dock most of its life and got unplugged only a handful of times; any any issue that the embedded diagnostics can pick up can also be picked up without any special recordkeeping by just running the diagnostics when you receive the device and verifying that it doesn't throw any errors out of the box.
If you've already got the trust me bro shadow subsystem I assume it's relatively cheap to propose having it keep more records; but I'm not really convinced of how much value is being added.
