Depending on laziness if fine, but depending on undefined strictness semantics for particular types is more fragile. Whether Int or Bool or whatever type has a strict or lazy accumulator in enumFromTo is entirely unspecified -- you can't look up the report to check.
Right, I understand that. But is there any reason not to keep the Integer version of [a..] lazy, given that we can fix the stack overflow problem without introducing strictness?
