>He's somewhat against package managers

yes and that is a design decision.

Its not just the dependencies bloatware, there is also an issue of accidentally pulling in a GLP license code base and several others. But if one wishes to make a package manager for Odin, they can do so and other Odin users may use it if they found it to be really helpful but from what I know, Ginger Bill will never officially support it as it doesn't align with his vision of the language.

There is nothing in the design of Odin that prevents a package manager from being created, in fact quite the opposite.

The decision, which is not design per se, is to not have an OFFICIAL package manager, nor even endorse a third party one.
