We continue to use SpaceWire where it's appropriate, and it was one of many options considered in the initial trade-study [1] that led to the creation of SatCat5. Among other things, many Aerospace-built cubesats have a laser communication downlink [2][3] that can reach 250 Mbps and up. It's not hard for raw sensor or video data to saturate a 1 Gbps link, and future missions may even need 10 GbE.
