I use to wish a simple standard would have been set about HPF LPF, I always disliked the concept of the wording.  High roll off is so much more to the point and obvious.  Low roll off, who could get that wrong?   After all, if you put a High pass filter on a source and you set it to say 80hz, you are still letting lows pass through, so the word high has almost nothing to do with saying high pass filter.  but if you say low roll off, you know what you are thinking about and if you need more low roll off you can easily process what to do in your mind.  Granted if you are looking at the actual slope and position on the spectrum this would not come into question, but if you are only reading labels from a plugin, and some plugins have them on opposite sides of the interface, this becomes like the class you always hated, but you got to pass.   Anyway another thing we just have to live with for now.
