No, there are no downsides at doing this, but I would suggest to instead either:
1) Set the Cutscene.defaultWrapMode property, or
2) Pass a WrapMode to the Play() method when playing a cutscene. There are several overloads of the Play() method, one of which takes a WrapMode parameter to tell what WrapMode to use for the cutscene in that play-through.
Once again though, if making Cutscene.playingWrapMode public works for you better though, that is totally fine 🙂
