You're welcome :)

To a certain extent, it does (see below).

You can, of course, try. Your chances of success would be better
if you tried to understand what kind thoughts have gone into it,
and why it's not working for you. The way you are putting it, it
comes across (to me, at least!) as "what kind of stupid design
is this" (cf. your words: "obvious", "defaults so bad"). I know
you don't intend that, but, as you can imagine, it won't fly if
that's how others perceive it :-)
If you want to learn more about that, the Linux MM ("memory
management") people have set up a wiki for that:
https://linux-mm.org/OOM_Killer
Enjoy :)
(and yes, on my box, more memory-hungry processes have a higher
/proc/<pid>/oom_score, so they seem to incur a higher risk of
being killed. The browser lies somewhat because it spawns quite
a few processes, but as a product of the propaganda industry,
lying is its second nature ;-)
