That was the goal of using them with SRV, which I think has worked out fine. >IOW, LDH labels.

When Dave started the work that led to 8552 there were already lots of underscored names used in other contexts than SRV, and we went to considerable effort to find and catalog them. You'll note the registry has a RR Type column since different _names are used for different RRTYPEs in different contexts.
