The documentation for wayland-server.h says: > Use of this header file is discouraged. Prefer including > wayland-server-core.h instead, which does not include the server protocol > header and as such only defines the library PI, excluding the deprecated API > below. Replacing wayland-server.h with wayland-server-core.h allows us to drop the WL_HIDE_DEPRECATED declaration.
