If you look at the /usr/bin directory of a Linux system there aren't any namespaces. There's 1,000+ binaries thrown into 1 folder, each with a distinct name and things work nicely.
Imagine if you tried to group those binaries into 1 or more folder driven namespaces. Where would things go? The amount of bike shedding would be endless and I don't think it would be a better solution in the end even if you managed to pull it off.

All of Joe's points in that post are spot on.
