  • New types were introduced for values

@corymhall I've cross-linked tracking issues with raison d'etre for each patch, looks like we cannot remove any of them yet.

I think we should go forward but if you have concerns about the RDS patch we can ask for an expedited bridge release and get that in first so we remove the patch. Thank you!
