I've worked at a few different shops, and I've seen that SYS2, SYS3, SYS4 HLQ convention a several times.
It's a hangover from days of yore, around about the 10th century CE, when link-listed datasets had to be catalogued in the master catalogue. The thinking went: since SYS1 files are catalogued in the master catalogue for IBM datasets, let's create SYSx HLQ's for non-IBM datasets that need to be in the master catalogue too. Not necessary in these enlightened times of course, but those original conventions tend to hang around.

I refused to put a sys3 dataset in the linkliest PERIOD. One of the reasons was that there would be a plethora of datasets and there was no accounting of who put this where and why. That got stopped after a year. I also didn’t want people that left any dirt they may have left either by accident or on purpose anything in the linklst (I won’t tell you about an incident we had that when the auditors found out they jumped on us up and down to get rid of them. I agreed but they wanted it done today and I said maybe next week as we had something major going in (it was 30+ years ago and I don’t remember details).
