I'll tell you why a flat object directory format simply isn't an option.
Hint: maximum directory size. It's limited by n_link, and it's almost
universally a 16-bit number on Linux (and generally artifically limited to
32000 entries).
In other words, if you ever expect to have more than 32000 objects, a flat
space simply isn't possible.
