Catalyst-controlled stereoselective cationic polymerization of vinyl ethers

We have discussed Ziegler-Natta polymerization for the past 2 weeks. A close ‘cousin’ of ZN is cationic polymerization of vinyl ethers. Get the following article: Teator and Leibfarth, Science, 2019, 363, 1439-1443. Review this article in 1 page max. Make sure you identify what you think are major advances (it is science after all) and where it is lacking.
NB: The subject for this article review is Polymer Chemistry.
DOI of the article in the question is: https://doi.org/10.1126/science.aaw1703
