The motivation is in #41443. I intentionally requested that these changes be made as small as possible because this is not a giant find-and-replace exercise. Some of the variables, functions, and flags that are being renamed in this process are used elsewhere within FB, but I personally don't know which ones. A large diff that attempts to replace several instances at once might have to wait on some internal changes, then encounter rebase/merge problems due to being stale, etc. I think it's easier to make many small, targetted changes.

Moreover, I did not expect so many people to take on these tasks so quickly. I created these issues primarily for my own tracking because I thought I was the only one who would want to do this work.
