Actually, a lot of MP3 encoders roll off at 16kHz. The latest version of LAME rolls off at around 19kHz only if you use the highest quality setting (-v0).
You are right in that the roll off could well cause a subjective improvement in quality. For one thing, it would get rid of all the noise above 20kHz dumped by noise shapers like UV22 (used in a lot of recordings).
Not that we can hear it anyway - hands up those who failed the 20kHz listening test posted a few threads ago! :-)
