Write your own kernel modules to duplicate the functionality of the /proc file system?

Because the /proc file system is designed to be the interface used to get such data. It's how utilities like "ps" get data, and even debuggers use the /proc file system as an interface into the processes they're being used to debug.

So you can't even use "ps" or a debugger to get that information without using the /proc file system.
