Well, that really doesn't make it bookmarkable as a permalink. The bookmark would rely on the actual post number in the topic, and not just the anchor. So, if you were to click on the icon and it just had the anchor, you're bookmarked URL might look something like this:
.....topics/208472/Re_Poll_Your_top_feature_you_w.html#Post208475
Post is still set to 208472. Anchor is 208475. Say you come back to your bookmark and 208472 has actually been deleted, but 208475 still remains. You'd get a message stating post cannot be found even though the post you're looking for is still there.
