IMO the most sensible. That way you can just clone readers/writers off
GitHub without authors needing to go through the hassle of setting up a Lua
rock. Having to do that will likely discourage people from publishing their
code at all. Also of course templates, filters, defaults all work that way
already. I have my data dir in my dropbox directory and symlink it in
~/.local/share, or rclone it on my Android devices (via Termux) where
dropbox isn't a regular storage directory.

Since they are already subdirectories of the dedicated pandoc data
directory `readers/` and `writers/` should suffice. Seven characters less
to type for each compared to `custom-*`.
