I did a bit of digging for you ;-)

The comparison with the_repository is from 7fbbcb21 (diff: batch
fetching of missing blobs, 2019-04-05), whose original version did
not have it, but was later amended with

  https://lore.kernel.org/git/20190405170934.20441-1-jonathantanmy@google.com/

And after that it survived across evolutions like b14ed5ad (Use
promisor_remote_get_direct() and has_promisor_remote(), 2019-06-25),
95acf11a (diff: restrict when prefetching occurs, 2020-04-07), and
finally a5183d76 (cocci: apply the "promisor-remote.h" part of
"the_repository.pending", 2023-03-28).
