as my Thai friends often say to me "Up to You". We all are well aware of past practices in entering/living in Thailand using various types of access. Yet as you discovered today the game is changing. And with introduction of facial recognition technology and fingerprinting along with an awaited introduction worldwide of an Thailand E-Visa online application process (which is currently in use in the UK among several other Thai Embassy/Consulates)...ones history is immediately known.
Make life less stressful, get the correct visa for your stays in Thailand.
Good Luck!
