Rewriting SDK paths is only needed when a text-based stub is an umbrella framework that does not include the contents of the stubs for the libraries re-exported by the framework. This is only the case for older SDKs. Once macOS introduced the dyld cache (and removed system dylibs) in 11.0, all umbrella frameworks in the SDK include the contents of their re-exported stubs. While rewriting newer SDKs is mostly harmless, it breaks Zig, which tries to interpret the paths relative to the SDKROOT.
