Wouldn't that cause a rather huge compatibility issue given that the
current oom_adj works in a totally different way:

! 3.1 /proc/<pid>/oom_adj - Adjust the oom-killer score
! ------------------------------------------------------
! This file can be used to adjust the score used to select which processes
! should be killed in an out-of-memory situation. Giving it a high score
! will increase the likelihood of this process being killed by the
! oom-killer. Valid values are in the range -16 to +15, plus the special
! value -17, which disables oom-killing altogether for this process.
