That wikipedia page has a support table saying IOS supports PWAs as YES and Firefox as NO is odd considering Apple requires Mozilla to ship a crippled form of safari on IOS, if Firefox could ship their own true application, I suspect they would have better PWA support as a differentiator with Safari.

"web bluetooth" and many other hardware APIs are Chrome-only non-standards that OWA pretends are standards and core features for PWAs.
