I'd like to see them lay more ground work for web apps but it's a tough spot and the easiest choice at the moment is to continue with AOSP.
Until that changes, webapps aren't going to sell.
Even Google tried multiple things to "sell" the idea of webapps (e.g. Polymer project) in 2011-2015 and failed.
Funny enough, Wechat kinda succeeded at webapps in China because there's a strong user preference to stay inside one monolithic "everything app".
Above that, not much would change for a few years anyway, because apps still target ancient Android versions.
