Gotcha. I suppose that makes sense as long as I undo some poor design and make sure that the 'exit' wrapper I have never attempts to call System/exit directly and always throws some suitable exception for interpretation at the top level. Right now my exit wrapper calls exit immediately if we're not in a REPL environment. Very few applications would care about the distinction (including mine) between unwinding a thread then calling exit, vs calling exit without unwinding.
Independent of my exit situation, I can still think of situations in which people may want to perform logic only when it was known to be a REPL environment. Of course in the worst case you can always add a -D flag to the JVM on startup indicating some 'interactive" mode desires. I'm not sure how that goes with repls from cider in emacs and such. Meanwhile I'm set with a workaround, and the points made on (app) vs. (-main (app)) are good if you always throw and never call exit down the stack.
