Depends on which embedded systems you look at.

For MID devices that's definitely true, but there are also today still 
cases where customers want fast startup times on < 200 MHz embedded 
devices, and when every second counts you don't want to add a
"Waiting for /dev to be fully populated" from udev to the bootup.

(And on my computer (whose Linux installation predates the inclusion of 
 devfsd (sic) into the kernel) the static /dev also still works fine.)
