Given that any "new" android device that gets shipped "soon" should be
using 4.9.y or newer, is this a real issue?
And if it is, I'm sure that asking for those patches to be backported to
4.4.y would be just fine, have you asked?
Note that I know of Android Go devices, running 3.18.y kernels, do NOT
use the in-kernel memory killer, but instead use the userspace solution
today. So trying to get another in-kernel memory killer solution added
anywhere seems quite odd.
