I agree that the names are misleading and we should probably provide better 
names. I'm wary of deprecating the old names because it'll create a lot of 
churn (some of which would be the right thing to do). Maybe we could just 
alias and warn when using the old name, leaving a decision on deprecation 
until some time in the future.
