Its been pretty quiet / same same for me. Haven't notice any change. Regarding carrying the passport with you at all times...I was reading a somewhat official statement here on Thaivisa about 1 or 2 years ago ( maybe even in the lawyer section when that was still around? ) that you do not need to carry an original with you, but have a photocopy of the important pages with you and be able to show the original in a timely manner. I have all my info uploaded to the cloud and can access it whenever needed. Every single entry in my passport(s) ever since I have been in thailand. Haven't needed it for immigration so far, but came in handy when changing something with my bank account and didnt have my passport with me.
