Has there been a followup to “A Closer Look at Deep Policy Gradients” for recent on-policy PG methods?

paper: https://arxiv.org/pdf/1811.02553

I checked connected papers and didn’t find any recent papers on the questions/issues raised in this paper. They seem pretty insightful to me, so I’m debating at looking at whether more recent methods have alleviated the issues, and if so, why.
