I think it's more of adoption of the feature just being not the fastest. Which is fine.
As @weston said Niagara launcher has supported private space recently and does it pretty well.
Also Kvaesitso Launcher was one of the quickest launchers to adopt the feature from what I had seen. Once again works pretty well.
It's a shame it's being quite lengthy for a majority of launchers to adopt the feature. But I like to be hopeful that the extra time will ensure that when they do adopt the feature that it will be well implemented and stable. Just like the previously mentioned launchers.
I'm mainly waiting for nova to get it. As it's the only thing I'm missing from the launcher right now and I love the extremely flexible control it gives you. Kvaesitso gives very flexible control too but it's not my style of launcher. I bet anyone who likes powerful feature packed search focused launchers might possibly take a liking to it though.
