Maybe, but right now it certainly isn't. Trying to migrate everything to devfs is likely to leave you with half of the neither-process-nor- device stuff in /proc and the rest in /devfs, leaving you with two kitchen sinks. Please don't try to do this.
Besides, I don't quite understand all the fuss about /proc. It's not overly hard to distinguish process and non-process entries (isdigit), and I doubt that readdir'ing over the respective wrong kind is much of a performance issue. So moving them elsewhere may at best create a lot of forced upgrades (i.e. basically everything reading /proc also reads non-process entries).
Some people argue that the non-process entries in /proc should disappear entirely. I don't want to re-iterate this particular discussion, just let me say that a large percentage of people putting things into /proc disagree with this view :-) Also let me point out that /proc entries are typically self-contained, which is a major advantage for deployment.
