Will downstream be able to handle {:error, atom()}?

Good call, yes it handles it:
$ mix ecto.load
** (Mix) The structure for Dummy.Repo couldn't be loaded: :enoent
however previously it was a slightly better error message:
** (Mix) The structure for Dummy.Repo couldn't be loaded: ERROR at line 1: Failed to open file '/Users/wojtek/dummy/priv/repo/structure.sql', error: 2
I will do something like:
{:error, reason} ->
{:error, "could not read #{inspect(path)}: #{:file.format_error(reason)}"}so that we have:
** (Mix) The structure for Dummy.Repo couldn't be loaded: could not read "/Users/wojtek/dummy/priv/repo/structure.sql": no such file or directory

I ran the test locally, with mysql-client@9.4 and it is passing now.
Thank y'all!
