How does one mark it apropriately?
The commit 51b1bd2 (oom: deprecate oom_adj tunable, see below) 
added it to feature-removal-schedule.txt, a patch for
Documentation/ABI has also been provided in the meantime, if i'm not
mistaken. 

And there is already a patch for openssh:

    oom: deprecate oom_adj tunable
    
    /proc/pid/oom_adj is now deprecated so that that it may eventually be
    removed.  The target date for removal is August 2012.
    
    A warning will be printed to the kernel log if a task attempts to use this
    interface.  Future warning will be suppressed until the kernel is rebooted
    to prevent spamming the kernel log.
