"Cregit" tool might be of interest to you, it generates token-based (rather than line-based) git "blame" annotation views: https://github.com/cregit/cregit

Example output based on Linux kernel @ "Cregit-Linux: how code gets into the kernel": https://cregit.linuxsources.org/

I learned of Cregit recently--just submitted it to HN after seeing multiple recent HN comments discussing issues related to line-based "blame" annotation granularity:

"Cregit-Linux: how code gets into the kernel": https://news.ycombinator.com/item?id=43451654

Of course, in your situation I guess such a tool would only help if other people use it. :D
