Initially I asked for an API in tools.deps which would return the -Srepro version of the environment. On further reflection, I think an API which returns the :config-files in -Sdescribe as a map would be more beneficial.
It would allow me to also ignore the deps.edn file in the local directory, which means I can opt into behaviour of my own selection.
In my case, I want to take an arbitrary deps.edn file as an option, and I want to combine that with the system one only, for the global environment (default paths, mvn repos and clojure).
