You know we're far from consensus on that one. Yes, the lookup part is cleaner, no argument there. But it's also cleaner to manage persistence of permissions, etc., on a real file system. You'll have a hard time arguing that. Sure, you can do it, but we can also do cached lookups. Both are hacks. However the lookup hack is invisible to the user and probably a bit less complicated than managing a virtual filesystem.
The third and final piece, dealing with dynamic device creation is solvable with a user-space component. Which, if all other things were equal, would be the preferred approach simply because it's that much less code in the kernel.
Personally, I think devpts and procfs should be replaced with userfs-type drivers wrapping sysctl for pretty much the same reasons.
