Because scripting languages are readable and modifiable, sysadmins will sometimes fix bugs that affect them by deploying just the changed .py files (rather than rebuilding an rpm package). Configuration management (puppet, Ansible, chef, etc) makes it easy to deploy and track hotfixes this way. If wheels are cached at rpm buildtime then this workflow will cease to function correctly for virtualenv and these bundled libraries. Since the bundling is an implementation detail that sysadmins will have no reason to know about until they want to hotfix whichever libraries are bundled, this is likely to take them a while to figure out.
Creating the wheels from the files on the system keeps the number of copies of files to a minimum. That, in turn, makes it easier for everyone involved to discover which files are the ones that do something.
