The motivation for this is that CompilationInfo really shouldn't explicitly know anything about CodeStubs. This is evident in the TurboFan stubs pipeline, which only needs to pass down information about Code::Flags to the code generator and not any of the CallInterfaceDescriptor silliness that Hydrogen has to push around, since TF has the Linkage class that encapsulates everything that is needed for the stub ABI. So, instead of threading CodeStub machinery through the TF stub pipeline, it is now removed from CompilationInfo and replaced by only the explicit bits needed both by the Crankshaft and TF pipelines in code generation.
