It looks to me that once a bounty is awarded, the post no longer has the visibility of a featured question. This one time I rather promptly answered satisfactorily someone's featured question, and OP offered to delay awarding the bounty, so that the question, and thus also my answer, stays featured longer. OP explicitly said that this way, perhaps the question and/or the answer can get more votes.
I told OP that OP is free to accept whenever OP wishes (if at all), and OP quickly did soon after. OP left a comment that this way OP didn't have to remind OP's-self to award it later.
So if it's true that a featured question is no longer featured once the bounty is won, then isn't that kind of harsh to the bounty winners?
Perhaps it's a good idea to have a special "featured answers" section, which is basically where featured questions temporarily goes after the bounty is won. Not only will this help the bounty winners get more votes (a nice bonus on top of the bounty points), but it's also good to showcase what stackoverflow community is capable of. That is, these are the "harder" questions people have asked, and here are the awesome answers that the community came up with. Everybody wins!
