is rolling back firmware dangerous? (on XO-1s especially)

[Adam Holt]

I used to do this all the time while testing XO-1s with different
firmwares, but want to check if the _process_ of rolling back firmware on
XO-1s is dangerous to the machine in general:

1) Are there risks to the _process_ of rolling back XO-1 firmware, EG from
q2f19 to q2e48 (Release 11.3.0) as used by many in Kenya?

2) Separate question: what risks might arise running Release 11.3.0
(required by many in Kenya) with more modern firmware like q2f19?
