exporting git commands in parsable format for constructing language-specific API for git CLI

While using git commands in my applications and reimplementing the
same stuff i found out i can just parse git docs then generate
structures and classes based on that; i have done similiar for
wordpress and its `wp-cli`, for example see:
https://github.com/bukowa/gowpcli/tree/master/generated

But `wp-cli` allows exporting all of the commands in a json format,
see: https://github.com/bukowa/gowpcli/blob/master/generate/dump.json

Is there anyone who thinks that would be benefical to do something
similiar for git, or maybe there's something done already and i missed
that? (parsing manpages / generated htmldocs is still a pain).

Thank you,
