I have no idea how to respond to that. It doesn't matter whether you
were there or not: this was the outcome we agreed on and here is a
proposal that should make working with the bug tracker a lot easier.

<maintainer>
<email>[address of the herd]</email>
<name>[name of the herd]</name> <!-- if you like -->
</maintainer>
Please provide some examples of when and how that piece of information,
"herd", is important.

There has never been a lack of ordering. The way bugs are assigned
since 2008 is as described in 2a. It requires not reordering the XML
tags. 2b says the order of appearance denotes the Assignee.

Go back in history and tell us how often herds change their e-mail
address. And how many metadata.xml files would have been affected. And
how that reflects on the future. And then compare that with the everday
chore of doing the extra lookup in herds.xml that shouldn't be needed
at all if the only thing you need is an e-mail address.

The proposal says we convert <herd> to <maintainer> in metadata.xml.
4d explains how you wouldn't need changes to repoman.

No, that's about changing herds.xml. This is about changing
metadata.xml. You can keep the herd information in herds.xml and make
metadata.xml a lot more easy to handle at the same time.

Maybe that should be fixed, then (including outdated information and
factual errors). I don't see how it would stop progress. It just needs
some minor rethinking.
