I have used those, my concern is that the load on those is parallel to the sheet, at 90 degrees to the axis of the fastener.
In my application the load path is inline with said axis- and would be attempting to pull the fastener out of the board rather than through it, if that makes sense?
I think it would be fine, get one that expands a lot.
Alternatively get a ceiling rose that attaches with three or more screws, that would distribute the load even further.
