People will use what works. But there is a limit. If you have two things, one of which does everything under the sun, and the other only does mostly everything, people tend to choose the first. The more people do this, the more "weight" the first carries. Until one day, it makes no sense at all to use anything but the first. Even if it causes you tons of headaches. The more different the two are, the less and less likely that you could or would ever switch. It's too big not to use. And so, building an alternative becomes a fool's errand. Nobody would use it, because there's just too many reasons why they shouldn't or can't.

(In case you don't believe me: it is now impossible to run a desktop without a half dozen Systemd shims, because the entire ecosystem is now hard coded to use Systemd. I know because my desktop is Alpine Linux, a musl distro)
