Details

There is some evidence that adding Paris bindings may cause linker virtual memory to increase during Windows PGO builds, which could contribute to these builds eventually running out of address space (bug 833881): https://groups.google.com/d/msg/mozilla.dev.platform/PVcbThwogSw/RtK-n7k4RPQJ smaug suggested on IRC that disabling PGO for the binding code (using NO_PROFILE_GUIDED_OPTIMIZE) might reduce linker memory, and that the code should already be well-optimized so it might not hurt performance.
I'd be interested in perf numbers here, yes. It might well be that PGO on this code is not really buying us much.
Linker memory usage isn't a problem now, so I don't think this is worth investigating.
