Not yet it isn't. In the current UI, to get to the source code, you have to
1. Find the little "Source" link and click it.
2. Find the "Browse" link, which is in a little toolbar right under the other little toolbar, next to the (less relevant) "Changes" and "Clones" links, which look visually near-identical.
3. In most (but not all) projects, hunt down the word "trunk" in tiny 13px text, and click it to see the main development branch.
Compare to GitHub or BitBucket, which just show you the damn code.
(Yes, I know you were joking, but I've been wanting to rant about this UI failure for a while now. And don't even get me started on Launchpad.)
