No need to pretend, because it never happened:

OK, the 4.19 filesystem corruption issue.

The fact that it was in the block layer doesn't exactly mean it didn't materialize as a FS corruption issue.

I never said the problem was in the EXT4 filesystem. The problem resulted in EXT4 corruption.

Quite sure the Git corruption issue WSL2 has isn't in Git either.
