That is still possible. The authors of those apps have to modify their designs to use foreground services - essentially, services that don't require a full UI but have to show their status in notification bar.
Most popular apps already use foreground services for use cases like yours. This restriction is to prevent dodgy spying apps that recorded without user knowing about it.
What do I do now if I want a skype or wechat voice call in the background while using the phone normally?
