Comment (by flixos90):

 Briefly summarizing today's office-hours proposed goals:

 * Introduce `*_network_meta()` functions using the Metadata API for direct
 interaction with the `sitemeta` table.
 * Add support for `meta_query` in `WP_Network_Query`.
 * Use the new functions in the `*_network_option()` functions. This gives
 performance benefits and allows us getting rid of the `alloptions` mess.
 The `*_network_option()` functions will continue to maintain their current
 hooks for BC, while the `*_network_meta()` functions will be clean as
 other object metadata functions.
 * Encourage using the new functions and use `*_network_meta()` in Core
 going forward. The `*_network_option()` functions will stay around for BC
 though, and should not be deprecated.
 * This will also benefit a future `/networks` REST API endpoint.

 See #37923 for related plans of introducing a `blogmeta` table and
 surrounding `*_site_meta()` functions.
