Unify vs flake-aspects vs custom solution

[kylebartz]

Currently using flake-parts modules extension to define the modules + classes being used. This has the structure of creating the modules in flake.modules.<class>.<module>. Would instead like a solution that solves the following:

• Have an explicit set of classes to avoid typos (nixos, homeManager, darwin)
• classes should be auto-defined for all modules to enable generalized imports/modules lists
• simplify host definition to have a singular global modules list that applies to nixos + all users (w/ additional user-specific lists)

Some existing options:

• https://codeberg.org/quasigod/unify
• https://github.com/vic/flake-aspects
