e historical inode numbers, all we have really
succeeded in doing is keeping the pid in the proc inode number.  The pid is
already available in the directory name so no information is lost removing it
from the inode number.

So if something in user space cares if we remove the inode number from the
/proc inode it is almost certainly broken.
