I used this to build python-orjson – a package that did not define the __provides_exclude macro as a workaround for the SONAME issue – locally in mock. I used objdump -x to confirm that the unwanted SONAME was not present in the compiled Python extension shared library, and I used rpm -q --provides to confirm that the RPM did not contain unwanted automatic provides related to the compiled extension.

As a follow-up, I used this to build rust-libcramjam0.2, which builds a C-ABI shared library with cargo-c and installs it in the system linker path, and I confirmed that the expected SONAME-based RPM provides is still present, i.e. libcramjam.so.0.2()(64bit).
