I like that the title is linked as permanent link, but I can see the point of the "link" being consistently there, however right now its behavior is not that of a permanent link, because if you have "style=mine" enabled for viewing entries, the link link will be in your style, whereas the the page title will be the permanent link without such display additions. So there actually is no duplication. Also I think it is perhaps misleadingly titled. I think the change that almost all links add "style=mine" rather than cut tags hasn't been around so long, but in any case I distinctly remember that soon after that happened I frequently wanted to take the link for the permanent link (as I was used to that pre-title linking and hadn't adapted to the change yet) and had to manually delete the style addition in my link html.
