Heh, I'm reading this thread after approving all of those patches.

The answer as to whether it's appropriate or not, is "it depends". 
Depends on the patch, depends on the age of the branch, etc.

In this case, newton is in phase 3 so normally it's only security or 
critical fixes allowed, but in this case it's so trivial and so 
obviously wrong that I was OK with approving it just to get it in before 
we end of life the branch.

So, it depends. And because it depends, that's also why we don't 
automate the backport of every fix made on master. Because guess what, 
we also backport "fixes" that introduce regressions, and when you do 
that to n-1 (Pike at this point) then you still have a lot of time to 
detect that and fix it upstream, but regressing things on the oldest 
branch leaves very little time to (1) have it detected and (2) get it 
fixed before end of life.
