The main problem here is that rpm uses compression libraries for creating and unpacking the package content. Unfortunately the number of libraries offering parallel compression are very limited. There is now support for multi threaded xz compression if compiled against xz > 5.2.0. You can set
%_source_payload %_binary_payload to "w9T16.xzdio" with the first number being the compression level while the second being the number of threads.
External tools are all configurable by macro. Switching to more modern variants is not something that rpm upstream is likely to do soon. It is the decision of the distributions to support them and change the macros accordingly. Upstream may follow the consensus of the distributions later.
