MainStage is still X86_64. Why are they not updating it to current hardware?

Does anyone know if Apple is not going to update MainStage to Universal of ARM64? Its X86_64 now and seems slow on my M4 Mac Mini 24GB Unified Memory, 1TB SSD. If I knew they were not going to keep it current with the latest hardware I will stop using it and move to Logic Pro or GarageBand.
