brtfs COW links and git

I wish git could use COW links. I wish I could put a large binary into git and have the only underlying filesystem operation be to cp --reflink and to save the metadata. There are a few complications:

How does it know which files to reflink?  attributes?  a size limit?
What does git gc do with reflinks?

Should diff-delta be reflink-aware? Perhaps it could query the fs for blocklists.

Before I dive into implementing this, I'd like to get your comments and advice, to maximize the chances of success. 

Thanks!
