Hello;

I was reading "Arch Wiki" and felt curious about that difference between

extra and community repo.

Some packages, such as "meson" is in the "extra" repo, whereas "ninja" is in "community" repo. The interesting fact is that - "ninja" is an implicit dependency to "meson". So why that is (ninja) in the community repo?

Also, some critical GNOME specific packages are part of the

community repo. Even, some compilers, like Haskell is also part of the community repo. What is the exact difference between extra and

community repository?

I wonder, Is it really important to have that split?
