I am aware about the changes introduced in Android 6.0/SDKVersion 23 regarding the app permission. There is excellent discussion on this topic in the below post.
"Android permission doesn't work even if I have declared it"
Now post Android 6.0, we require to verify and seek various permission during run-time as discussed here.
With this, Does adding tag in AndroidManifest.xml will have any meaning/use case post Android 6.0 targeted devices only?. Or we can remove these entry.
