Re: git: ff0c7816db69 - main - Remove UPDATING entries from old branches.

Please revert this. We keep older updating entries on purpose. You purged
way too much. Let's chat about how much to remove in arch@. They are for
more than just source updates, so your reasoning is wrong. They are also
there for users updating their products which can have a larger leap in
time. We've traditionally kept closer to 5-10 years here for that reason.
