i think flakes may offer this using their self fixpoint, which may be made available more widely using the likes of flake-parts (which.. we otherwise had mixed feelings toward, see #528).
as such, we may want to:

verify such potential performance gains
investigate ways to reconcile this with facilitating consumption through dependency managers other than flakes (also see #518, https://discourse.nixos.org/t/froyo-a-tasteful-way-to-organize-your-nix-code/70823)

some of the components we build can be used in different places, including production vs (different) tests. to save on build time, it may be of interest to deduplicate such computations by reusing cached results when possible. i think flakes may offer this using their `self` fixpoint, which may be made available more widely using the likes of `flake-parts` (which.. we otherwise had mixed feelings toward, see #528). as such, we may want to: - verify such potential performance gains - investigate ways to reconcile this with facilitating consumption through dependency managers other than flakes (also see #518, https://discourse.nixos.org/t/froyo-a-tasteful-way-to-organize-your-nix-code/70823)
