The situation is different for roundabouts and motorways. In both cases in absence of the tag oneway it is assumed to be yes for these elements, but you should add a oneway tag explicitly for motorways (for roundabouts not).

Looking at taginfo confirms that 99,64% of all motorways have a oneway tag: https://taginfo.openstreetmap.org/tags/highway=motorway#combinations

i.e. adding the tag is recommended and also done in reality.

From all junction =roundabout only 18% are combined with the oneway tag
