Some of the Steem will spill back over to Bitshares. The Bitshares community decided that the rate of innovation was too fast, they wanted to slow it down so the platform could become more stable. The Devs wanted to continue so Steemit was born. They have not fully abandoned it. Alot tof the things that ae working here will trickle back in Bitshares. It was a matter of timing for Devs, should they fight the community and miss the opportunity window for something like this or jump on it and use it to improve Bitshares down the road.
