Because "man rc.conf.local" says:

But good point nevertheless. Removed prometheus_flags from
rc.conf.local entirely, ran "rcctl start prometheus" and still:
...
prometheus_flags empty, using default >--config.file
/etc/prometheus/prometheus.yml --storage.tsdb.path '/var/prometheus'<
...
prometheus: level=error ts=2020-03-01T21:10:47.505Z caller=main.go:717
err="opening storage failed: mkdir data/: permission denied"
