First, this sounds like an accidental, potentially completely innocent, failure of standard procedure, e.g., at Univ of Minn (where I am) and many other places, either the department head or some functionary has a yearly discussion with tenure-track people, giving them formal advice on how they're doing in all relevant categories: research, teaching, service.
Second, unless there's something seriously amiss, no information is imparted... It's more of a confirmation that everything's on track.
Third, for a variety of reasons, these days the actual getting-tenure seems to be put off as long as possible by the institution(s). One easy reason is that, if the person will put up with it, the institution has a longer time to judge... There seems to be some positive resistance to "early" consideration for tenure. Yes, one can directly tell the dept chair that one wants to be considered... but departments are well aware, if only for HR purposes, of the "tenure clock" on all non-tenured tenure-track faculty.
As to whether it's worthwhile to take initiative about tenure consideration... hard to know. "Rocking the boat" is generally not helpful, but sometimes people are tooo apathetic.
No way to know for sure on any of this apart from asking someone in your dept who knows the standard procedures there.
If your publication record is good and your teaching is ok-or-better, and you are a good citizen, probably nothing to worry about.
