Then you're lucky. We have two 2017 MBPs and one has a broken R key. Broadly speaking (a) the failure rate is really high and (b) the fact that it can only be fixed by a complete front plate replacement makes this a punishing error. In the old days if a key broke you could just replace that key most of the time. Here you need to replace half the chassis, which necessitates a trip to the Apple Store.
