Do you put drill a small hole in your thermostat?

Been drilling holes for years! I was taught to do it by same curmudgeon that taught me how to weld with coat hanger and torch. And before I get flamed into oblivion for crude mechanic skills that same codger was lead mechanic on National Champion SCCA race car. I am dating myself but he beat the collective brain trust of Quaker States group 44 in DP with Datsun 2000 roadster. Guy was brilliant. Ya get bored google number 54 Barton special Road Atlanta Champion. I fetched beers and washed parts for him growing up.
