IMO, since you're making a pack you know the entire available inventory, so you can and should control redundancy.
To take defense of Solars, building a complete mod as he is doing, including many new weapons (with sprites), new technology tree, crafts and so on, needs a huge investement and is heavy to drive
I am currently making my own mod (for more than a month ago) including most of nice available resources, and it is not always easy to deal with :
- interferences between mods (especially research, ...)
- mods stored under "Complete Mods" section but being in fact regularly evolving
- keep game vanilla quality (listOrder, translations, ...)
Give your feedback, make propositions and suggestions, try to convince with arguments, but keep in mind to have some indulgence
And in any case, you are able to get a big mod, and make some adaptations to fullfill your own expectations
PS : anyway, I agree with your point of view about redundancy
