I don’t think consolidation, compromise, and coming together in one common direction are the hallmarks of open source at all!
Filesystems, service management/startup, audio output, desktop environment, package formats/management/distribution, programming languages, shell, and so on, and so on - all have many, many options.
Open source is, if nothing else, fractured… it’s about choice, flexibility, and re-inventing the wheel not because it really needs to be re-invented, but because it’s fun to do so and useful to have something that perfectly fits your requirements.
We’ve made room for many package formats for decades, and will continue to do so for decades to come I’m sure.
