LIVING here and bouncing in and out at land borders with overstay stamps is not the same as having a small overstay in your passport and entering the country :P BUT how about we agree to disagree.
About the only time 100% an overstay stamp will hurt you is:
If they ever open back up, you can't get a tourist visa at the thai consulate in Penang Malaysia with an overstay stamp
AND
you can't get a Thai elite membership with an overstay.
