Due to having to install Xcode for nillerusr, some macs that either don't have space to upgrade OS version or don't have MacOS version Sequoia (15.6) supported. It'll become literally IMPOSSIBLE to get Xcode from the App Store due to it needing to be 15.6+ so that means you can't build nillerusr, if you can, try to find a way for macs to use nillerusr for this exact problem
