Did you test it (note the "UNTESTED" in the subject!). My usual system for this is getting upgrades and being
flaky at the moment.

Sure. "struct mce" is visible to user space via /dev/mcelog. But the only user is the
mcelog(8) daemon ... and it was never updated to look at the usable_addr field. So
returning it to "pad" status is fine.
