It may have more to do with the timing of the service interval.
If you are doing a radiator flush like every 50K miles for example, the thermostat may be due for a replacement at the second flush interval.
Replacing it won't hurt, regardless, as the part is about $30. I wouldn't replace it unless you are noticing signs of high operating temperatures lately...
