Yes, it is rallying against KASLR as a means to defeat known privilege exploits. Well, in that narrow context he has a point.
In the broader scheme of things, I fully expect OSes running on the Mill to use some form of ASLR, especially in user space. There have been internal discussions about it.
Canaries, however, are not needed.
I do hope OSes fully embrace the finer grained security the Mill provides too.
