Having the visa that is the most misused at the moment, and not is meant to live in Thailand permanent is always a risk.
You might not see it as a downgrade, but in fact it is.
You now have to leave the country once a year for example.
If I was staying the whole year around in Thailand I would have applied for non-o retired, and not for DTV.
As soon as they make it possible to get the 1 year extension online, just as the initial visa, I would certainly choose for non-o.
DTV just has to many risks of changing requirements.
