I think anyone agree with benefits of devfs. Limited number of dev
files really existed hardware in /dev is one of them.
And then question: is someone plan to port devfs?
No, nobody does. Also, it is not clear whether a port would be good or
whether rewriting it from scratch would be better.
Then I try to do this job. :)
As starting point I plan take FreeBSD devfs, but any suggestions are
welcome.
