I'm puzzled by this new version which extensively relies on somewhat magical
HTTP redirection. Instead, can't we fix hgwebdir to be able to host hgweb at
'/' URL, and add explicit URL to show the index page hidden by it?

That will be useful without subrepos. Currently we can't see the index page
'/foo' if we have a repository '/foo' and '/foo/bar'.
