The developers of the software you use say they made a newer versione and the old one will not be maintained. Nothing stops you from using it. My Windows install is still running Windows 7 and I know Microsoft isn’t maintaining it, and many apps don’t support it. I accept these limitations.
Same thing with Xorg. Same thing for the few people who refused to move from Haiku alpha 4 to beta 1 because of package management. We can’t help them, and we can’t make software that pleases everyone. They are free to maintain a fork if they want to. In most cases, that doesn’t really work.
