That's a good question...

Since ultimately I'd like we get hash files for the packages, and make
it an error when the hash file is missing, we'd have to handle those
cases in a consistent way.

There are two options here:

  - add a real hash, and break older releases when the file is updated
    upstream,

  - add a 'none' hash, but loose the detection tht upstream has changed
    (but the autobuilders would tell us if that change breaks the
    build).

I'm afraid the only possible solution if we want to have a hash is the
second solution (but with a comment explaning why it is so).

But until we make the .hash files mandatory, we can just not add it for
non-versioned upstreams. So I'd say we drop that one.

Yann E. MORIN.
