static inline is bad. Generates way too much code that the linker is unable to optimize and remove on final link. This causes these symbols from every class in godot-cpp to be included in the final link, even if completely unused by the lib. Removing changes a basic shared library from being ~1.5MB on almost all platforms to now ~200kB.
