Agreed. Downloading stuff to your local machine should require a
confirmation step.

Agreed. Also, the current "fix" (two variable and three functions!) is
overly complex. I propose that their be three options in the
defcustom:
- 'org-attach-directory (the default)
- user entered string
- a function (which could be set to `org-download-dir')

Also, sending files to external command/shell script for processing
often breaks if you have spaces in paths due to quoting issue.

Agreed.
