IME of 1x9 .. using a shortened chain AND a long-toothed, unramped chain-ring ... I would still lose the chain frequently.
Not saying it can't be done, but you'll need to get lucky setting it up .. and bear in mind it only takes 1 drop to scar the heck out of your cranks or chainstay - I speak from experience!
Almost the same setup as bonesetter here, (XT short mech rather than SRAM)
Very, very occasional chain dropping, certainly not enough to be a nuisance.
Oh, forgot to say, I also use a BB which can be adjusted laterally and then fixed which allows tweaking of chainline, so if chain's dropping in, move chianring in and visa versa. This makes for zero dropping off
My only 1 ring set up was always dropping off! Frequently, when shifting up (to a smaller sprocket) the movement sets up a "ripple" along the chain which would drop it straight off the ring - really annoying! Sorted with this.......
Which is now surplus and for sale 
Its when you lose the chain and kneecap youself on the shifter/stem
then a chainguide is worth it 
You can all roll your eyes now. I'm going double or tripple 
If people who claim that their chain doesn't ever come off riding off road on a 1x9 set up, without a chain device, knew that what they were ostensibly saying was that they are basically really slow off road, I suspect they wouldn't be so quick to make their point.
rubbish, some of us can just set up a bike properly
oldgit...triple??? 
Well double then 
I have a bash guard and an N Gear Jump stop - works for me.
for CX all purpose bike, i'd go normal CX crank and rings, mtb cassette with long cage rear mech, plenty of gears there
Don't use one as we run out of stock before I get a chance to fit one
Short chain
White industries single speed ring
Mech wound back a bit
Chain has come off once on long dh.
Will fit a mrp bb mounted device one day.

Oh hang on you're being serious aren't you.
Built up a new bike Friday night, and had to change the chain device as my LG1 wouldn't fit. Couldn't get the chainring bolts out, so had to bodge a gamut device without the bash plate for yesterday's ride. See here:
Tight chain, short mech, unramped chainring - pretty much all the rules described in this thread. Still lost the chain once when going fast through a a rooty section at Woburn. Without a proper device i1x9 is no good for anything other than bridleway riding.
I'm pretty sure the chain would have stayed on if I was jumping of a 10" bit of tarmac in the high street though.

just relating the facts, i.e. you can't stop the chain dropping on 1 x 9 (assuming you have tried it and are not basing your "facts" on something you've heard or dreamt up) and i can stop the chain dropping with simple set up
14 months and you havent had the chain come off the lower part of the chainring and gradually roll off the ring as you descend a rough trail?
Take that bike up here and even the tame stuff will have it off in an hour.
Its when you descend and stop pedalling that it will hop over the teeth at the bottom.. then work its way off.Sometimes its possible to pedal it back on but depending on how long and rough that track is.. you will lose it.
14 months?
14 freekin months?!
:::walks off muttering fourteen months shaking his head with a frown:::
the chain might not come off without one and with the correct set up, but I would rather ride with confidence knowing it's not going to come off rather than worrying that it might
I have an e13 XCX which weighs about 70g

why put an ugly heavy device on and just carry it around when it's not needed?
Strange point to make when you ride with a long cage mech.
