I just found this feature trying to solve some locking issues when running cargo in parallel, are there any plans to stabilize this?

Basically No. The git index is an implementation detail, and one that may change (cc #8890). The main user (that we know of is) of this is crater and they use a nightly build, so don't need it stabilized.
