I knew long before and used them occasionally to get webpages as an "app" via the browser. If I was going to build a website it makes sense, as long aa you design your page for mobile viewing... One of the services we use for work relies on PWA as the only way to get it on your phone, has been like that for ~8+ years.

Makes me think of other under-utilized things... My personal website was WAP enabled back in the early days of mobile internet. 😆
