Historically we have only used/updated plugin engines when a certain cordova-cli/android/ios version was needed because of a new feature required by the plugin.
Nowadays, most plugins still (technically) support old cordova-cli/android/ios versions, but we don't really test on those versions, so can't be sure. And a few recent PRs I've sent are technically breaking because I removed old iOS code for iOS 6-8 support. Those versions have not been supported in cordova-ios for a long time, but the plugins still supported them as they didn't have engines or the cordova-ios version used as min supported version still supported them. So, what I'm proposing is to add engines to all the plugins to require at least cordova 9 cordova ios 5.1.0 cordova-android 8.0.0 We should do it before we do a major release of any plugin, but don't mean we need to do a major release of all plugins right now, just have it in mind before we do a major release of any plugin. And I would also like to remove the "protective" engine all plugins have that points the next major version to cordova >= 100 thoughts?
