That, or at least something like it, is quite doable - will put it on my list.

What I asked for is something which could replace

mpiexec -x FOO -x BAR -x FOBA -x BAFO -x RR -x ZZ ..

(which is quite tedious to type and error-prone for the users) by setting some dreamlike value, e.g.

export OMPI_PROVIDE_THIS_VARIABLES="FOO BAR FOBA BAFO RR ZZ"

At least some envvar, whose content would be simply added to the comand line, could help:
export OMPI_ADD_2_COMMLINE="-x FOO -x BAR -x FOBA -x BAFO -x RR -x ZZ"
