Disclaimer: I do not make decisions on what gets into clojure.core. Here is a page that gives some reasons why most things don't get into clojure.core: http://dev.clojure.org/display/design/Why+Feature+X+Was+Declined
More specifically on if-all-let and things like it, many people seem to disagree on what they think is the most natural behavior for a variant of if-let with multiple bindings -- whether it should be 'and' or 'or' behavior, for example. Obviously that doesn't preclude a well-defined alternative from being adopted, hence the page above is probably a more accurate answer.
