It's one thing to have differently licensed code in-tree that's built as a separate utility (like that persistent-https tool), but another if this is going to be something linked to git itself. My understanding is that such a thing could not be legally distributed as a binary (e.g. by Debian et al), so the users will be limited to those willing to build the two pieces from scratch locally, i.e. similar to ZFS on Linux (which I think is still the state of that ...). But I'm not a lawyer and all that. Another possibility is to get the library to dual-license itself, running "git shortlog -sn" on it it seems it's mainly written by one contributor, with a relatively short tail of others, perhaps they'd be willing to dual-license at the prospect of having git use it?
