In a special and successful niche I'd be reluctant, too. It's a similar thing to a successful affiliate showing less successful operators how to jump on the bandwagon.
I have also known of featured sited get booted from the organic SERPs, so it's no guarantee.
However, on the up-side, linkbait and the accolade of being classed as a quality site would be a positive benefit.
