> gets in the way of having a deeply-nested project hierarchy"

Do people actually want deeply-nested project hierarchies?

For example, from a real-world, full operating system, the deepest path I can find[0] is in a build directory and 184 characters:

> "./ports/lang/python26/work/Python-2.6.1/portbld.static/build/temp.XXXXXX XXXXX-vHEAD-amd64-2.6/XXXXXX-home/XXXXX.git/src/ports/lang/python26/work/Python-2.6.1/Modules/_multiprocessing"

(Names changed to protect the "innocent.")

    $ mkfifo ../names
    $ find . > ../names &
    $ python
    >>> with open("../names") as f:
    ...   l = 0
    ...   nm = None
    ...   for n in f.readlines():
    ...     if len(n) > l: l, nm = len(n), n
    ...   print l, nm
