I'm a sysadmin. I use that "gross hack" for about 1.5 years now. I even write my own utility for it (and the other rt scheudling stuff).
Normal unix behaviour is useless if you want to
a) work on a machine b) have long-running non-interactive jobs
Anyway, both irix and hpux have this feature (and yes, it uses a different scheduling class), and I'm wondering all the time why linux (the best os available) lacks so much in this respect ;)

I actually use nice +20 or nice +100 or whatever quite often. Thats very unintuitive. Having this a different class is much much saner ;)

The disadvantage is that you need a special utilitiy, but anyway, I just use rtprio (my own invention) to start and change scheduling classes, we just need a tool (maybe nice/renice could be extended...)
