Since supporting other users is necessary for the long term success of the platform, any change that helps curators achieve their proper reward will be a good change, at least in my opinion.
I suppose it must be very tempting for bigger users that always get huge upvotes on their posts, to simply upvote their own posts and earn authors and curators rewards, but by choosing to not do this those users can really prove their commitment with the well being of the platform.
Curators make huge contributions by finding great posts that aren’t very visibly, so they need to feel and be appreciated by everyone.
