Is there any downside (other than the cost of the fittings) to using these couplers?
There is no downside so long as you don't change the inside diameter of the pipe. Some of the connections you mention are not "full port", meaning that they are not the same ID.

Technically speaking you are adding about 5 feet equivelant of straight sch-40 PVC when adding the coupler but that's not enough to worry about.
