Another viable path is early access for 'free' testing and a dripfeed of a few sale, and then effectively a second release. Have your cake, and eat it, if you can live off a small slice initially.

It frontloads a lot of 'post release' development devs might want to do. Not that its easy by any means, but it is kind of a 'hack' since storefronts will treat your existing game as a new release.
