Why don't we support customized times for throttling out of the box?

I am referring to the code in parse_rate, in SimpleRateThrottle. Why doesn't it support rates such as 1/5m? Here's my custom code that I had to implement in order to achieve this objective:

def parse_rate(self, rate):
        """
        Given the request rate string, return a two tuple of:
        [allowed number of requests], [period of time in seconds]
        """
        if rate is None:
            return (None, None)

        time_keys = {"s": 1, "m": 60, "h": 3600, "d": 86400}

        num, period = rate.split("/")
        num_requests = int(num) if num else 1

        duration_str = "".join(filter(str.isdigit, period))
        duration_unit = period[-1]
        if duration_str:
            duration = int(duration_str) * time_keys[duration_unit]
        else:
            duration = time_keys[duration_unit]

        return (num_requests, duration)

Because having a simple constraint for the more typical case is an okay and reasonable design decision.

(Yours is also an okay design decision, but it's not the one we've opted for.)
