I would lean to the second option, that stop calling READ_AT_SNAPSHOT without a 
timestamp repeatable reads. Rename it to READ_CONSISTENT looks good to me but 
we may also need to concern about backward compatibility.  My main concern of 
calling it repeatable read is the users may get confused when the same bound is 
given, different results are returned (because different timestamp is chosen).
