According to what I've seen, people started complaining in 182, not 187.

See for example

http://patchwork.linuxtv.org/patch/13085/

which is a thread where you were involved too..

See also the arch linux thread:

https://bbs.archlinux.org/viewtopic.php?id=134012&p=1

And see this email from Kay Sievers that shows that it was all known
about and intentional in the udev camp:

http://www.spinics.net/lists/netdev/msg185742.html

There's a possible patch suggested here:

http://lists.freedesktop.org/archives/systemd-devel/2012-August/006357.html

but quite frankly, I am leery of the fact that the udev maintenance
seems to have gone into some "crazy mode" where they have made changes
that were known to be problematic, and are pure and utter stupidity.

Having the module init path load the firmware IS THE SENSIBLE AND
OBVIOUS THING TO DO for many cases. The fact that udev people have
apparently unilaterally decided that it's somehow wrong is scary.
