It often works that way - when binary RPM compression switched from xz to ZSTD in Fedora recently, it was reaaly just about making sure the tooling can now read ZSTD while keepin xz support in place for compatibility (basically msking sure it links to ZSTD and can use it at runtime). Then just switch the Fedora build system to compress binary RPMs with ZSTD when they are built and you are done. :)
