Man - Apple has the worst customers.

Your filevault password has not been compromised by any T2 issue.

The secure enclave is rate limited.

If you are such a valuable target, then the key logger needed to get your credentials can be installed T2 or without T2 issues. Once "they" have that they can decrypt your drive.

The number of folks who are targeted at this level with physical direct access is relatively small. Even for state actors, REMOTE compromise is MUCH more appealing.
