+1 I think you need to deprecate something like that and not just yank it, but removing the doco is a good first step. I have M2_HOME set even through I don't technically need it but that's how I switch versions of Maven. I have M2_HOME set, it's a symlink, and i just flip the symlink to change versions of Maven. That's probably my quirky way of flipping versions but I've probably had that in there for 10 years.
