Don't worry , cars have had this for many years, the re mapping won't be an issue they just dial stuff out and alter parameters , the future mot testing can be an issue ,, bikes will likely be subjected to exhaust emission testing in the future,
euro 5 was when more significant consequences like limp home were built in by legislation, on new stuff an electric coolant secondary pump can cause limp home to cut in,,
fair point though, bikes will be more reliant on diagnostic equipment , it would be interesting to see if they go to the standard OBD socket which may allow generic code readers of the P codes and stuff,,
