I'm only fine with fixing the kernel pointer fields in some way.

But moving forward any other change to the procfs file is simply
a waste of time.

You should create sysfs files and add logic to your tools to look
for them and use them if they exist.

Your forward path _SHOULD NOT_ be continuing this procfs versioning
madness.  Use something sane and do the work to make userland start
to be ready for this transition.
