I think the goal of the series is to eventually get to the point
where nobody uses the_repository variable. If repository.c, which
consists of a set of service routines that work on a repository
instance, defined it, showing willingness to implicitly rely on
the_repository through things like get_oid_hex() (which would rely
on the_repository->hash_algo), that would go the opposite direction,
so everything, other than the definition of the_repository variable
itself that allows other files that still do rely implicitly on the
variable to link with it, in repository.c would actively want to
refuse to use services only available to those who define USE_THE_*
macro.
It is a similar pattern we took when we weaned ourselves off of
the_index compatibility macros. The read-cache.c was the central
thing that defined the in-core index services, and it was the first
thing that lost the_index compatibility macros like read_cache(),
add_file_to_cache(), etc. that implicitly worked on the singleton
the_index instance, while everybody else still relied on the
singleton and services that implicitly worked on the singleton.
