Dear Guix folks, I saw the lines in Artanis pkg info:
-----------------------------cut---------------------
 (delete-file-recursively "artanis/third-party/json.scm")
 (delete-file-recursively "artanis/third-party/json")
 (delete-file-recursively "artanis/third-party/redis.scm")
 (delete-file-recursively "artanis/third-party/redis")
-----------------------------end----------------------

I understand these lines are aiming to unbundle guile-json and guile-redis,
however, recently I've unbundled them in vanilla Artanis. So there's
something changed.

You may need to keep third-party/json.scm and third-party/edis.scm in the
next release since they are the wrappers, and it's possible to make further
abstracts then. In addition, there are necessary renaming operations for
compatibility.

Best regards.
