Is Upgrading To Mesa 11.1-devel Worthwhile For Radeon R600g Users?

With last week's release of Ubuntu 15.10, Mesa 11.0 is part of the open-source graphics stack. Unfortunate for those with an AMD GCN GPU that uses the RadeonSI Gallium3D driver, Mesa 11.0 on Ubuntu 15.10 is built against an older version of LLVM that doesn't allow the OpenGL 4.1 support to be exposed. For RadeonSI users, I'd say switching to Mesa 11.1-devel + LLVM 3.8 SVN is almost a must once installing Ubuntu 15.10, but is it worthwhile for R600g users?..
