Yes it was.  The benefits of dynamic devices were considered to
outweight the downsides of having to mount a devfs instance.

Actually I disagree.  Once you write the simple devfs ruleset it is a
single command to instantiate a new /dev.  You don't have to worry
about making each individual device node N times and possibly making a
mistake.  Of course you probably have a script to do this now, but
that just means you need to adjust your script as part of your
migration strategy.

To put it bluntly, it's something you're just going to have to get
over :-)
