I have good news. First, I have tried some tasks where I lacked GPU performance, and it is much better now. Not sure what was improved since Qubes 3.0, but it is better in both PVMs (Debian) and HVMs (where GPU emulation is probably handled by stubdom).
Second, I got OpenSWR working on Debian 9 and it is not so hard. OpenSWR is a part of Mesa 12 (this is the reason why I haven't tried it with Debian 8…). When Mesa is compiled with OpenSWR support, one can use it by environment variable GALLIUM_DRIVER=swr. Unfortunately, OpenSWR seems to be neither in Debian repository nor in Fedora repository. Fortunately, Mesa can be compiled with OpenSWR by just adding few options. I've compiled it on Debian 9 using apt-get source, few modifications and debuild. I can share details. I did not go the clean way (with ensuring dependencies are specified correctly etc.), but it is working. I haven't much time for benchmarks, but OpenSWR is reportedly much faster than llvmpipe. Since Qubes 4 will have Linux-based stubdoms, it might be worth using OpenSWR there if it proves to work well. (Maybe not as a default option.) BTW, when switching to Qubes 4, where will be the output rendered – in AppVMs, or in stubdoms?
