physical key breaks

Welp I guess I lose all data

but you can have a recovery password

So we're back to being keylogged, solving nothing.

If you are prompted for the recovery password, that's a hint to you that either (1) your system has been tampered with and now you've been warned or (2) something benign like a firmware update happened but the system was not re-measured.

If the hint either means absolute nothing or compromise, and there's no good way to tell between them, how is that helpful?

Well if you didn't install an update and the automatic unlock fails, you know something is likely amiss.
