That beings up a good point...water heaters do accumulate residue minerals from heating up water. Many times, these P&T valves do open with an increase in either higher temps or/increase in tank pressure.
These minerals will not let the valve seat properly and thus leak.
It's not a bad idea to flush your tank regularly, removing the 3/4" plug. Some use dielectric rods, other do not.
6 months ago when draining, I had so much crud to flush out it reminded me to do again soon. Something that you should also do to your home water heater tank annually.
If you do flush and clean the valve regularly, the valve may not be necessarily replaced.
