It's worth noting that this patch is different from the other mechanical patches. I do agree that we should remove this unused portion of the slab API. Likely this was built for testing purposes.

CC'ing Junio, who I found introduced this in a84b794ad "commit-slab: introduce a macro to define a slab for new type". Looking at that diff, the realloc portion did not appear to exist in the previous in-degree-specific version of slabs.
