@soviut @sil But it's those same flows where this technology tends to fail most spectacularly. Go trace your local food delivery system w/ WPT or a low-spec device. Here in the US, the UIs of Grubhub, Caviar, Opentable, and many others have been totally destroyed by this tech.
I've been getting variations of "we need this to be built in a heavyweight JS framework because 'it's an app'" for years and years, and I'm not going to take the theory as valid when ~all of the practice cuts against it.
