Not only generators. For systemd we have to consider

/lib/systemd/system-generators/ (24 packages)
/lib/systemd/system-shutdown/ (6 packages)
/lib/systemd/system-sleep/ (10 packages)
/lib/systemd/system-preset/ (6 packages)
/lib/systemd/network/ (1 package)

systemd does not support reading scripts/files from a /usr/lib 
counterpart and we'd have to patch various places in systemd to allow 
that. Those patches should be simple though.

For udev, it's a bit trickier.
While udev supports reading udev .rules files from /lib/udev/rules.d and 
/usr/lib/udev/rules.d, udev allows to run programs via RUN+= or 
IMPORT{program}=
If not specified with a full path, it will look up the binary in /lib/udev
There are quite a few packages which hard-code a full path, like e.g.


90-libgpod.rules:ACTION=="add|change", SUBSYSTEM=="usb", 
ATTR{idVendor}=="05ac", ATTR{idProduct}=="129[0-9a]", 
IMPORT{program}+="/lib/udev/iphone-set-info"

Moving everything from /lib/udev to /usr/lib/udev would break that 
reference.

Then there are also quite a few .rules files which don't hard-code the 
full path. For those we'd have to patch udev to lookup the binaries in 
/lib/udev and /usr/lib/udev.

Not quite sure, how we'd coordinate that. Maybe only automatically move 
the .rules files and then file bugs against packages shipping helpers in 
/lib/udev to do the migration manually (by moving the helper to 
/usr/lib/udev and updating the .rules files accordingly).

A rough estimation suggests that this affects 60+ packages.

# apt-file search -x ^/lib/udev/  | grep -v rules.d | grep -v hwdb |
