To me, this starts sounding like a legendary "userspace suspend" versus 
"kernel suspend" support fights many years ago... Since that, I have 
_sometimes_but_rarely_ been luckily enought to get my laptops 
recovered from the suspend states successfully...

And as the kernel patches allows disabling the schedyles feature either via kernel 
build parameters, boot parameters or at runtime _if_you_ really want, I do 
not understand why do you complaint if there will be much better defaults 
in the kernel immediately once you just build and boot the new kernel.
(I really do not plan to start converting init-rd boot scripts from 
all of my computers systemd way of doing things in near future...)
