I think especially with the proliferation of systems running on essentially the same code, we're going to see more projects that support multiple chains. The Beem python library supports or semi-supports at least four chains last I checked, so more and more of the things people are building will be mobile between chains. This is a good thing for the sustainability of the projects and should eventually be for the chains as well. There's no reason to pull a dLive move when you can just add chains and keep supporting the old ones.

Commerce seems like a weird place to start, though; Whaleshares are incredibly cumbersome to use as cash right now, and most of the others have the same problem. Steem is way ahead on liquidity.
