I have noticed that most of the plugins don't use the engine tags or have them set to cordova 3.0.0 or 3.1.0 which are very old.
As we drop support for old iOS/Android versions when updating cordova-ios and cordova-android, what is our policy for iOS/Android versions support in plugins? Right now people can use the plugins on very old versions of iOS or Android despite we don't support them on the platforms, as the plugins engines are set to 3.0.0 or 3.1.0 on most of them. Should we start updating the engines to newer cordova versions? or even fine grain it to cordova-ios/cordova-android versions? I have noticed that we even have engines for iOS versions using apple-ios on the engine tag https://github.com/apache/cordova-plugin-wkwebview-engine/blob/master/plugin.xml#L35 (but not sure if this really does something as the plugin can be installed/used in older iOS versions and what works or doesn't work is controlled in the code) Or just say that the old Android/iOS version is not supported by Cordova anymore if someone complains about a plugin not working?
