"Before"...
I put Rick's answer below too, in strict/correct code it can be used but
what examples (except yours) ?
Maybe I missed it, never saw the use of null since a long time, but I
can be wrong
Do you think it does worth the complexity for the operators we are
talking about ? w3c is forced to define something as null, would look
strange and not serious to define it as undefined in specs, but in
reality this is let to the appreciation of developers (who usually don't
care), and for comparisons/default, null will, I think, never be used,
then it should probably behave the same as undefined

Nobody (except w3c) is using null, or when someone is using it, it is the
same way as undefined, and it is not explicit (ie a||b or a==b, not
a===null), I remind some old code where we could see the use of null but can
not find a single example of recent code, then the new operator(s) should
treat it the same way I believe, the problem is 0 here
Your experience isn't necessarily universal. I've used null before to
mean something different than undefined.

There doesn't need to be an explicit check for undefined - anytime null
is used as an intentional place holder and its value would be
_otherwise_ undefined counts as well.
And for your information, I am not w3c and I use null frequently (the
same way w3c uses it).
