A rate would be pretty much unhelpful... It changes. And you'd have little or no control over how long the rate was calculated. You'd be at the whim of whichever developer/designer decided to use. They might like a 5 minute average (Shades of Cisco SNMP stats for CPU). But 5 minutes isn't good enough. They might like a 10 second average, but you only poll every 60 seconds... So you lose 5/6ths of the data.
Yes, you could conceivably save the data every second internally to the SNMPD and accept a value for making the calculation. But the S in SNMP is for SIMPLE.
Polling for totals and calculating the difference/polltime is the only way you can make your own decisions on frequency and be accurate.
