I guess the question is: is os13 usable at this stage?
Should power management be be inactivated in the control panel?
Are there appropriate/recommended powerd.conf settings for the XO-1 at this stage?

So SLEEP basically drops connections and then the XO-1 fails to DIM or BLANK. Setting SLEEP time _after_ DIM and BLANK has the expected behavior. 
In all cases the XO fails to reconnect to the preferred network after wakeup from SLEEP.
I settled in DIM=180, BLANK=480, SLEEP=600. No huge power savings but at least the build is usable.

sounds like something's going wrong for you that isn't going wrong
for me:  dim and blank happen correctly after sleep for me.

i haven't tested networking robustness on os13, so can't speak to
this.

please file tickets for the problems you're seeing, and attach
dmesg output, as well as powerd.trace.  (enable powerd tracing
with "sudo powerd-config =trace-on".)
