There are several answers to that...
Samba remains portable, minus Windows 2000 emulation.
It is easy to enhance ext2 in the same way.
If ext2 and BSD don't evolve, they die. Problem?

Not "both" but "all 2042". That would kill performance.
With tiny little (sub-)files, the stat data starts to take up
a significant chunk of space.
There is also a correctness issue. This reminds me of the bugs
in Linux threads. We don't really define the larger container,
so the little bits (threads or sub-files) get out of sync.

I hope you realize that "podfuk" will not be very successful in the US.
The sound of "podfuk" brings to mind sexual activity with vegatables.
Businesses in the US are very concerned about sexual harassment lawsuits.
