Guess I'm fine with that, just didn't know as it was apparently half-way 
supported, as rules.d/, keymaps/ etc. honoured --libexecdir

Gentoo used --libexecdir=/lib for udev, so in the process of getting ebuilds 
for 185 working nicely, I adopted that dir as it seemed to be supported at 
first.  There might be - or from what I recall actually are (lvm2) - packages 
that use /lib/udev/rules.d/ as well, so that needs some more investigation if 
systemd-udev can't be made to install there.  OTOH note that apart from a 
possibly smoother migration path, I'm very much im favour of moving things to 
/usr
