I assume that among those who prefer those areas of the game that are best enjoyed on multiplayer servers, only a few would care about those whose aspirations are best met in singleplayer creative mode, but anyways, we're still here, just mostly under the radar (or might be, I certainly am, among a few other diehard RP-ers who work in SP and showcase on SMD).
Recent mechanical developments have left the essential engineering areas of the game in a mess, and we're still waiting for the new power- and chamber system to be finalized, and the weapon update to be even released properly... So perhaps there's still some hope that life will replenish in StarMade after the aforementioned stuff will happen.
And then we will get the Universe-update. If all goes well, it's reasonable to assume that that will create some frenzy of activity, if all won't be lost by the time that update hits.
