or should we get along with er R?

Neither, there should be no brackets (no CS inference) and the name is not well chosen. It should be something like ext (as in https://github.com/math-comp/real-closed/blob/table/theories/table.v)

for the sake of discussion (because ext looks a bit short and very generic while extended is a bit long): eline R for extended real line?
