For system problems, RGN is often unnecessary. And apparenty customers often don't think it's necessary or they'd add it to their installation defaults. But perhaps the real reason is that if a dump SDATA "include this" option is made the default, there would generally have to be a corresponding "do not include it" option and perhaps the developers did not want to do that (or, way back when, perhaps the extra bits needed for such options were too precious to spare).
