I find "unlimited PTO" enough of a warning signal that I think "not explicitly stated" is an excellent description of what it gives you. And, yes, at least one former workplace switched us from "25 days, plus Bank Holidays" to "unlimited PTO". With pretty much everyone in my team complaining that we preferred an explicit limit than a nebulous non-explicit managerial capriciousness.
