There is no limit to the number of cwp files in a folder. I use per-project audio folders and almost always have several active cwp files (and older versions too) in the folder above the audio folder. The only time I make a copy of a project is to make a backup or use the "Save As" to another folder for the final cleanup. I can copy the other cwp's from the original folder if I need them.
I wholly agree.
Using Per Project Folders gives you MUCH more flexibility when troubleshooting, and you can be assured that all of the relevant audio files are located within the project sub-folder.
The Global audio folder was designed to be used when creating new projects using ctrl + N (because it has nowhere else to store the audio)
In my opinion, you are needlessly complicating your entire folder structure.
A simple test - say you want to completely delete and entire project including all its audio?
Using global, audio, you would have to to hunt down every audio clip/track associated with the project and hope they were all named correctly when you delete them. This can be complicated if at some point during the project's life cycle you change the project name. Sonar will NOT go back and rename all of the older clips with the old name.
Using PPF's, all you need do is delete the entire folder from Windows.
