High level questions:

1. Is this change NFC, or is there some important change reviewers need to be mindful?
2. I see some methods are now virtual when they weren't before and some (Strting)switch statements have increased in the number of cases they handle. Have you had a chance to double check neither of those is affecting the performance of the linker?
