My only use of the pipermail archives is to find permanent URLs for
mails I want to refer people to. My usage goes as follows:

1. Google search for a post.
2. Paste in the URL to an email.

Or, if I have the post already (usually in my email client).

1. Check the date and subject of the post.
2. Go to the pipermail article by month, and scan the list for the
subject and author.
3. Click on the link, check it's the right email, copy the URL.
4. Paste it into my email.

I don't use the archives for reading. If the above two usages are
still available, I don't care. But in particular, the fact that
individual posts are searchable from Google is important to me. And in
the second usage, having a single scrollable webpage with no
extraneous data just subject/author and a bit of threading by
indentation speeds up my usage a lot - the UI you linked to (and the
monthly archive page with the initial lines of postings on it) is FAR
too cluttered to be usable for my purposes.

So basically, what I'm asking is what would be the support for the use
case "Find a permanent link to an archived article as fast as possible
based on subject/author or a Google search".

Finally, how would a transition be handled? I assume the old archives
would be retained, so would there be a cut-off date and people would
have to know to use the old or new archives based on the date of the
