hopefully encourages them to change the checking mechanism to check whether the system can do it, rather than just checking if the OS name is in their list

Even if they stick with a hard-coded list of OS names, providing a supported, documented mechanism whereby one OS can pretend to be another / override the actual OS with a different OS of your choice would be a workaround.
