Yes, I and others have used ref=* and it seems OK. Example: https://www.openstreetmap.org/node/6763249794 However I have also seen others use local_ref=* as at https://www.openstreetmap.org/node/2877506734
I'm not sure that there is any purpose to "local_ref" unless it is somehow different from an official "ref". I have used only stop numbers noted from surveying signs at bus stops. Earlier this year there was brief discussion about accessing NSW Transport Open Data - for example https://lists.openstreetmap.org/pipermail/talk-au/2020-February/013568.html but no one has yet acted on that, as far as I know.
