Sure, but removing it is also not needed :)

I disagree. NEWS items should stick to their core business, and that is
informing users of imporant changes that affect their running system. We
provide the reference so one can easily Google it if you want to know more
backgrounds, but the back story of why this was done is really not all
that important. I'd like to keep these entries as brief and
straightforward as possible, and don't expand into background information.

We can extend this part a bit further, yes. It's a pity though that it's
already a bit late for that for most upgraders, but I'll change it
thanks for your suggestions.
