  ### To "reproduce"

  Install a fresh VM, as explained in the bash script's doc, and run it:

  ```
  apt update && apt install wget -y
  wget https://raw.githubusercontent.com/bitcoin-core/bitcoin-maintainer-tools/main/delete_nonreduced_fuzz_inputs.sh
  bash delete_nonreduced_fuzz_inputs.sh
  ```

  ### To "test"

  * Keep an eye on coverage stats, to ensure it doesn't drop
  * Re-run the script, to ensure it is "reproducible" to some extent
  * Anything else you think is important to test or review
