as i understand, SRR enables high performance IPC, which is a requisite for good graphics performance under x11 - is it realistic to use it in place of unix sockets where available?
This is certainly not a thing which we should resolve in our packaging process. We try to concentrate in this bugzilla mainly on problems with packaging, not huge structural changes in the programs.
Please, file a bug in the upstream database at https://bugs.freedesktop.org/enter_bug.cgi?product=xorg or discuss this issue on the upstream development list at firstname.lastname@example.org.
But, with an upstream hat on, while fast synchronous IPC is certainly an interesting area of research, X is an async protocol, so it's pretty unlikely that we'd use SRR.
