iPhone 8 locked permanently in "Unavailable iPhone" mode. Is it possible that in the future, there will be options to retrieve the data?

My old iPhone 8 went into a disabled "Unavailable iPhone" mode today. Is there any chance in the future, many years down the line, that third party data recovery services will be able to retrieve the data? Read here that government forensic specialists are able to get through the encryption if it's below ios 14.7 but I don't know if that's true or not. Not sure if anyone can answer this question but just asking in case it's worth hanging onto.
