Are we sure we don't break any user-facing tool with it? Tools might use this to
"remember" how the device was authorized this time.

That's why it was highlighted in the changelog. Hopefully a
Thunderbolt developer can confirm if it is a non-issue.
Documentation/ABI/testing/sysfs-bus-thunderbolt does not seem to
answer this question about whether authorized_show and
authorized_store need to be symmetric.
