Sorry, which parts of the proposal are you responding to? The article is more specific than "more rigor". Are you objecting to the higher p-value threshold? The independent confirmation?
The author argues that a single higher quality confirmatory experiment will be able to replace gathering lots of statistics for exploratory experiments:
> Unlike clinical studies, most preclinical research papers describe a long chain of experiments, all incrementally building support for the same hypothesis. Such papers often include more than a dozen separate in vitro and animal experiments, with each one required to reach statistical significance. We argue that, as long as there is a final, impeccable study that confirms the hypothesis, the earlier experiments in this chain do not need to be held to the same rigid statistical standard.
Do you disagree?
