Thoughts on switching from FAT32 to ext4 as the file system that is exposed to the Telsa?

Tesla's officially docs say it must be FAT32 but this is not true, the car will mount and happily write to ext4 (tested on my model 3 software version 2019.20.4.2).

The big advantage of this that I can think of is a journaled file system that won't get corrupted so easily plus ext4 supports multiple mount projection. This would allow us to mount it by the pi and copy files off it live. That would mean no more multiple images, we could just construct one very large image and work off of it.
