Thank you, Josh looks interesting. I will need to look into this. At first read it looks like the end result is not a brand new Git repo that combines/merges a bunch of repos. I am not sure if a proxy is going to work well with Gitlab CI
If you can define exactly what you mean by "keeping history" (i.e. which operations do you want to support, and in what context?) I might be able to tell you how to do it :)
