Well you can still do that, the current scripts will get run that way
too.

udev is such an example. I want it to run for every hotplug event. To
do that with the current scripts, I have to either modify the current
scripts to always call it (not a big deal, I have CVS access :) or add a
handler for every type of device, and every type of those devices.
devlabel is also another type of example. The author of that had to
persuade us to modify the scripts in order to get support for his
program. I don't want to be a gating function, with this simple
proposal, he could just dump the devlabel script into the /etc/hotplug.d
directory in the proper place and everything would just work.
I've also been hearing from lots of other people (interestingly, not
publicly, I guess they like to stay hidden for some reason) that also
hook the hotplug scripts. They have usually been either recommending
that their users patch the current script, or just replace the current
ones all together (thereby loosing the module load functionality) in
order to support their devices. This proposal would also help them, and
their users.
