I think asking application authors to patch their apps to use that
interface is a lot less nice than say asking them to add this key, and
then if we decided that using the extant oom_adj kernel interface was
the way to go, the desktop UI could set oom_adj when launching the app
(after fork, before exec if it's inherited, otherwise take the small
race condition and set it after invocation).

We don't right now.

We can work out the exact details of how all the components interact
after the fact.
