As per various threads on the devel list, we should consider renaming RTBC to "Ready for committer review" to ensure that developer expectations more clearly match reality.
Sounds reasonable, but wow, is there going to be a lot of stale references to "RTBC" on d.o. :( Guess we'll all have to get used to "RFCR" instead.
I don't suppose any brilliant wordsmiths can come up with a new phrase with the right meaning that retains the acronym, huh? ;)
