Sarge is using devfs in its installer and its been used widely for a
long time now. I myself have been using devfs _without_devfsd_ since
the first 2.4 test kernels and found (and patched a few) very few
programms that won't work. There is hardly anything that uses device
nodes directly and I know of no case where it makes sense to limit the
source to a single device. Any software that has no option to change
e.g. the dsp device to be used is just plain buggy.

I submitted a patch for init and getty to transparently translate
between devfs and non devfs names over a year ago so even that little
anoyance could be easily delt with.

So I'm all for sticking with maintaining devfs names. The only thing
obsolete in devfs is the suposedly race codition riddled code. The
nameing scheme is way better and more orderly than the obsolete flat
/dev structure.
