I don’t think PWA will gain the traction needed to dominate the market. Native development is still better for the most part. I also don’t believe Apple wants anything to do with PWA and the only reason they added support in 10.3 was due to the fact that they were purging their AppStore of what was effectively website apps. With Apple holding a significant share of the mobile market I can’t see the reasons why you would want to invest in a PWA when there is such a large user base with devices who don’t treat PWA as a first class citizen.
