Wow, back to high school. They don't track attendance in undergrad even. Why do companies need this sort of information? If the person is important to the meeting, them being a no show will be pretty evident. If they are so irrelevant to the meeting that they could just dip out and no one would be the wiser, why are they even wasting their time in the zoom meeting to begin with? Just email whatever information you need to get out if the zoom meeting is going to just be an announcement or one sided lecture.
It also wouldn't be hard to write a little script that automatically connects you to zoom meetings that are coming up. You probably only need a few lines of bash to write your own if you have a tool like icalbuddy where you can grep for upcoming zoom meetings in your calendar.
