I am pretty sure the compiler will generate the correct code if we just don’t say anything.

Removing it causes compiler errors, but =default works fine.

There are several appearances in for example CDMProxy.h and related files that are not being changed. In the GTK/WPE ports, these things are built when experimental features are enabled and I don't recall if we have them enabled in EWS so they won't fail. Anyway, I don't know if you're taking a step by step approach but those would need changing as well or things will break on our side.

GTK/EWS developer builds have experimental features enabled.
