This is not a good reason. People who are used to read JSON will stumble
over this all the time because it is so uncommon.

It might actually make sense to optionally disable showing extensions.

You also forgot to mention that you explicitly disable handling
`<pathspec>`, which I find a bit odd, personally, as that would probably
come in real handy at times, especially when we offer this as a better way
for 3rd-party applications to interact with Git (which I think will be the
use case for this feature that will be _far_ more common than using it for
debugging).
