But it isn't always null right? It does get set at least when you log in right?

There are 2 ways that cookies can get set or deleted. The first is via a
Set-Cookie HTTP header and the 2nd is by Javascript setting the document.cookie
property. I only see this happening in Krang.Cookie.set(). Is it happening in
any auto-generated JS or templates?

Well, we can't just ignore a missing config because we'll then possibly send
data in the wrong charset. The only thing I can think of is to find a
reproduceable test case from start to finish and then start putting some
console.log() statements everywhere you can and see where the CONFIG cookie goes
away.
