Let me know, when it will be possible to try.
FWIW I started some bindings for libgit2 but
I got stuck... Basically because it's overwhelming.

I got stuck trying to bind "git clone" [1]. Here is the signature:

|int git_clone(git_repository **out, const char *url, const char 
*local_path, const git_clone_options *options);|

It requires a double pointer "out". Then it also
has a "options" which is a "git_clone_options" struct
which in turns requires |another struct named git_checkout_options.

I am still not sure how to declare function pointers in
guile-bytestructures and libgit2 make heavy use of those.

Maybe it's too complicated, instead I can try to
regenerate my wiredtiger bindings [2]. What is
specific about it is that it has functions pointers
in struct.
