Curious, is the syntax described in If used, alias names should refer to a path vector in the alias data relatively new? I don't think I had seen it till today
https://clojure.org/reference/deps_and_cli#_paths
It's been supported for quite a while.
I use aliases-as-data for several things (but not paths).
Looking in the source, around the chase-key function which is part of the implementation for that, it's been in the code for at least 3 years @vemv
Thanks much!
