- * attention to, to the sum of the number of pack files in all the
- * repositories processed so far). This can be removed once the object
- * store is no longer global and instead is a member of the repository
- * object.
+ * NEEDSWORK: when reading a submodule, the sparsity settings in the
+ * superproject are incorrectly forgotten or misused. For example:
+ *
+ * 1. "command_requires_full_index"
+ * When this setting is turned on for `grep`, only the superproject
+ * knows it. All the submodules are read with their own configs
+ * and get prepare_repo_settings()'d. Therefore, these submodules
+ * "forget" the sparse-index feature switch. As a result, the index
+ * of these submodules are expanded unexpectedly.
+ *
+ * 2. "core_apply_sparse_checkout"
+ * When running `grep` in the superproject, this setting is
+ * populated using the superproject's configs. However, once
+ * initialized, this config is globally accessible and is read by
+ * prepare_repo_settings() for the submodules. For instance, if a
+ * submodule is using a sparse-checkout, however, the superproject
+ * is not, the result is that the config from the superproject will
+ * dictate the behavior for the submodule, making it "forget" its
+ * sparse-checkout state.
+ *
+ * 3. "core_sparse_checkout_cone"
+ * ditto.
+ *
+ * Note that this list is not exhaustive.
