I just tried A=1 L=0 with the following operating systems, all fully 
updated with whatever latest versions is shipping to normal people.

Windows 10
MacOS 10.11.6
iOS 9.3.4
Android 5.1.1
Linux 14.04 LTS

They all did what I consider "the right thing". They autoconfigured 
addresses and used them, and they did DAD on the link.
