I'm not particularly biased in favor of UDI. As a matter of fact I think the UDI

if it becomes important later on, great, if it definitely dies.. so be it..
I am wondering though.. will DragonFlyBSD keep newbus, perhaps as a userland API?
FreeBSD is making changes there (inheritance in kobj() ). What about busdma? I
guess you wouldn't want to break new drivers coming from FreeBSD.
I can't really comment on Newbus, but I am sure we ought to keep
something like busdma around, until a better API comes about.
Not only because it's a nice interface, but it is used in NetBSD
and FreeBSD and OpenBSD, so I guess we should stick with it.
The KLD framework surely needs an overhaul though. I am
thinking about integrating changes from FreeBSD-CURRENT for
the KLD framework, when I have some free time in my hands.
