Yes it was shocking to learn about the file format. I reverse engineered the stuff that I need to know and its a complex mess of noodle soup (later found a description of it, but its not fully documented by Mozilla either). I am surprised that Thunderbird still uses this ancient and inefficient format.
Thunderbird still uses mbox. Maildir is incomplete and experimental.
I really wish we could use maildir.
