Well, that thread is 12 years old, and no one followed on that proposal. So it seems people have different priorities, working on other stuff that they consider is more valuable ... You can either work on this yourself and write a patch, or try to convince others it's worth working on. But you didn't provide any information that'd demonstrate the jitter and that incremental checkpoints would improve that.
