But GObject isn't a simple type system on top of C, A C compiler wont catch any GObject type error since everything is about casting "types" with macros, a C compiler has absolutely no understanding of GObject type system. I don't believe one second writing GObject code is simpler than writing C++ code, having looked at serveral GObject codebases.

No one claimed gobject c was simpler to write than c++. That would be a foolish claim.
