There’s a problem with that. When you’re looking at a release group, you have that “Read more…” link, but when you’re looking at a release, all you have is the WD link in the sidebar. It’s kind of annoying to have to click on that link then scroll to the bottom to find the WP link and click it. And as @IvanDobsky says, not everyone knows about the relationship between WP and WD, so a lot of users are just going to see an unfamiliar link and ignore it.
I’d much rather have the generated WP link right under the WD link in the sidebar.
