There are many configuration options in BB that must be defined at

You can activate both as the default (with cost of some byte overhead of
code size), and let the user of the binary decide which mechanism he
prefers, or even flip temporarily (without system interruption).
Users that want a functional solution will not probably care much
about the underlying implementation.
Exactly that means, using only one mechanism, is forcing those users to
do it in a specific way, with all sort of consequences.
Those who want to tailor BB to fit their preferences most likely don't have a
problem with building
their own BB.
Ok, and what's than wrong with my intended approach? You will be able to
opt out most of the parts, if you like, even the parser / handler (think
of you want to handle device management in a script without reinventing
the event plug mechanism). It is a modular system, just tie those
functions together you like.
A device handler could be:
#!/bin/sh
while read -tTIMEOUT message
do
# now split the received message
...
# and setup your device node entries
...
done
exit 0
... or think vise versa: Let someone find a new, ultra solution
mechanism, but still want to use the conf parser / device handler back
end. So opt out the plug mechanisms and let in the parser, then use a
small external program with the ultra new solution mechanism (until it
may be added as another optional mechanism in Busybox, like netlink).
A modular system, put together the required parts. Only cave-eat should
be, you need to fire up some kind of a service daemon for the device
management system ... else this start of the service daemon (fifo
manager is just another name for it) needs to be coupled with some other
part ... which hit Laurent's wishes, poking me for clarity and
functional separation.
