@wjwwood it would be really nice if there were (e.g.) a version macro for the RMW interface so that a single source can be used to cover some of these changes. I suppose RMW__PUBLISHER_OPTIONS_H_ and RMW__SUBSCRIPTION_OPTIONS_H_ could be used as a proxy, but it feels a bit dirty.

@eboasson that's a good idea, can you open an issue to track that? This isn't the first time we've needed to change API in rmw and it won't be the last, so I think having tools for you to have a "single" source is out of scope for this pr at least.
