I don't worry about checking in when with a group jump, but when I do solos and especially solos at a new dz (getting a feel before trying to find someone to jump with), I ask another jumper on the load to make sure to see me on the ground. Make a point to find them and ask how their jump went or something as a check in.
If a DZO wants or has a check in system, great, all the better. But it's still my responsibility 100% to lookout for myself and others firstly. I'd use a DZOs check in as a back up, people on the jump run can figure out something's wrong faster.
Edit: Its simple to police yourself and be responsible.
