Yeah I think the final performance hit should be much less given that those numbers are very early development tooling releases. I also predict that William and Peter will save us from a situation where we have to worry about it :-P Then the other worry will be how big Universal Binaries will be - the macOS DMG is already weighing in at 750mb+ and I hope the UniversalBinary doesn’t push it north of 1gb….
