Desktop Applications (20+ for every one task)

Hi
Wrt:

Note:
1. I dont pretty much understand why do we have so many alternates to nautilus. Maximum 3 developed for standard DEs should have been enough.
2. Why there are more than a dozen desktop environments, each trying to give icons and interface, for the very same purpose. Again Cinnamon/Xfce, KDE and Gnome were more than enough.
3. I like Kolourpaint more than others, personally. But still there may be some lags in it, but having gpaint, and all others for same single task.
4. So many panel applications/docks...
5. Cd/Dvd Burning: k3b is my choice, but there are so many others, for each desktop!
6. Audio/Music players, more than many, competing each other.
7. Ending the basic default list here. (others: terminals, archiving tools, office, web browsers, task manager, calender, image viewers, video players)
Why not just have 3/4 main projects, just like Distros: Debian, Fedora, LFS, and rest if the developers are interested to branch them from the original projects, as derived Distros, but still linked to the main project, and if there is positive development in the downstream, then all the upstream can also benefit from it. Though I do assume, it doesnt exist, yet.
Still some good alternates (2 or 3 only) ... seem missing, in Linux world, to:
1. xsane
2. Hplip
3. etc
And again nothing solid exists against, wrt same inter collaboration between developers:
1. AutoCAD
2. Some Adobe Products
3. etc
Thankyou

1. This point is not related to WMs or their applications, extensions etc
2. This point is more related to basic Desktop applications.
