This option can't be added to both init and action, because the rsync exclude mechanism is used to select the files to send, so would delete all non-changed files. It's only relevant during init anyway, as after that no excluded files will be made on the destination.

This is useful to me because it allows excluded files to be easily removed on the destination even if they were not excluded when they were created.

I can make a separate PR with documentation changes if required. Do you think this needs tests?

Thanks!
