Yes, that is the primary reason for adding hashes. And we do want hashes
for those sensitive packages. However...

... there are a few other good reasons we accept hashes:

  - it ensures a broken download is detected, so the user quickly knows
    that the tarball is broken because of the download; sometimes,
    upstreams breaks their distributions (e.g. the recent sourceforge
    breakage...).

  - non-compliant downloads are removed (rm -f) so they are not
    accidentally used in another context (e.g. I do share my BR2_DL_DIR
    with other stuff).

  - consequently, it helps the autobuilders prune their failed
    downloads.

But in the end there is no clear policy, except:

  - we *do* want hashes for security-related packages;
  - hashes for other packages are a nice bonus.

Yann E. MORIN.
