    ----------
    If you clarify it to require and in bounds endpoint, you need
    to do two operations.

So what, it's only (subseq a 0 (min 5 (length a))).

    No big deal, but I don't think many
    users would find it confusing that the operation stops at
    end of string if the endpoint is out of bounds.

I think they would.  (subseq a 0 5) should always return a string of
length 5.  Under your scheme, it might return a shorter string.
