Fortunately in the desktop space there's little reason to care what the big names are doing. There will likely always be a distro out there that does exactly what you want it to, it'll likely always be Gentoo, and there will probably be enough folks interested in the space to bring those solutions to binary distros as well.
It's been especially interesting to me to watch Alpine take over the mindshare that Slackware had back in the day. As long as there's enough people on un-"official" distros to file bug reports with software vendors, there's hope for the users.
