Two functions missing from Version 1.7`?

[VersionReview]

Hi,

showErrorMessageForUnsupportedBrowsers: window.AddToHomeScreen.SHOW_ERRMSG_UNSUPPORTED.ALL,
allowUserToCloseModal: true,

After updating from 1.7 script didnt work....is there a reason why the above parameters are not working any longer?

i think these features are really good: sometimes as a PWA maintainer you dont wont your visitors to use a mobile browser, because user experience lacks. so a nice option therefore was for those browser which do not support PWAs: "Use Google Chrome, install the PWA as an app or you cant use my service"

so as a pwa mantainer you can decide: allow users to use the site just by browsing it in unsupported browser OR ALTERNATIVLY show a layer which permits users to use the site via browser
