B Evolving Dark Energy?

    In the course of brushing up on my dark energy, https://arxiv.org/abs/astro-ph/0207347, The Cosmological Constant and Dark Energy, I noticed Peebles, et al, raised the possibility of evolving dark energy. Curious, I elected to do some further checking and turned up this rather startling claim; https://arxiv.org/abs/1406.2209, Model independent evidence for dark energy evolution from Baryon Acoustic Oscillations. As seems all too often, I was quite surprised I had not noticed this sooner and was further surprised to learn it has apparently since been corroborated; https://arxiv.org/abs/1503.04923, Is there evidence for dark energy evolution? Just how big a deal is this, or am I just living under a rock?

    As I read it, there are still some statistical uncertainties in the analysis done by Sahni et. al (2014), as apparently collaborated by Ding et. al (2015), summarized in the latter's para. 3.

    I would not take this as sufficient evidence for dark energy evolution.
