Looks great 🎯👌 - I left minor feedback, but for me it's good to go, anyway.

nit/ it seems to be an artifact of V2 refactoring - neither LoggingOrRUMsender nor LoggingAndRUMsender do exist and instead we use CrashReportSender.

Great work 👍 another approach would be to send a single "crash" message on the bus, and make the Logs Feature consume that one instead of "crash-log". It would simplify a bit the implementation, but it would have to print a more generic warning if the crash is not consumed at all.

I can also do that if you prefer. It depends if we want to give importance to the fact that the crash is consumed by a specific feature, or by any feature.
It's a bit easier to debug a crash not appearing in Logs/RUM with the current implementation as the message is feature specific. But it will generate a noisy warning each time a crash is treated if the developer doesn't want to activate one of the features.

Yes, I am for simplicity :) I think we would benefit from sending the crash only once on the bus, mostly because it will save an encode/decode operation on the message-bus and it could be consume by any Feature. Also, this warning won't have much visibility as it will be printed when the app restart only.
