That was never an envar for public use, but rather one that was used
internal to OMPI and therefore subject to change (which it did). There
are a number of such variables in the system - we try to indicate this
by not exposing them via ompi_info. Of course, you can independently
discover them with a printenv, but we would not recommend relying on
them.
The list of reliable envars is provided here:

Note that this begins with 1.3 and does not apply to any prior releases.
