Greetings,
I checked out the wiki page. Thank you for typing that up, Jonathan.
I vote for keeping tags (hey GB to MB -- we can keep tags), and I really like:
https://wiki.koha-community.org/wiki/Git_Splitting_and_Shrinking#Howto_use_Koha_main_repo_with_localization_repo
It's still pretty clean in terms of getting all of Koha.
