No, it just means that we've not spent time between those 2 RC, but we will try to take care of those issues before v0.8 final.
BTW, my point of view on Hybrid CPU/GPU Path Renderer: I consider it mostly a technical demo of Hybrid CPU/GPU rendering, from my point of view BiDir is always better (i.e. converge faster) than Path tracing so it isn't very useful to accelerate something that is "never" used. This is the main reason I'm not spending time on Hybrid CPU/GPU Path Renderer after the initial development.
Things will change when SPPM and/or BiDir will be accelerated by Hybrid CPU/GPU rendering; in this case Hybrid CPU/GPU will provide better performance than CPU-only renderer in all cases. I plan to add Hybrid CPU/GPU to LuxRender SPPM renderer soon after the release of v0.8.
I'm also planning to write a PathGPU Renderer for LuxRender based on SLG 100% OpenCL PathGPU tracer (or better based on the new PathGPU2 I'm working on). It will be a very particular beast with only 1% of LuxRender features supported (i.e. a kind of SLG with the LuxRender front end) but it will as fast as SLG is.
