The enforcement of the 90 days per 180 rule has gone off and on since at least 2008. It's always been meant to empower immigration officers to selectively deny entry and not as a blanket policy. It's an anachronism from times when Thailand felt itself over-populated with permanent tourists. I can't imagine it being enforced at all now, since Thailand is suffering from the polar opposite condition.
If you're concerned about possibly being denied entry, just go get a tourist visa (or any other visa for which you qualify), since the policy only applies to visa exempt entries.
