If these are easy for the snapcrafter to create, then I suggest we just
use SHA2-384 or greater. If for some reason we are limited to things
that upstreams already publish then we could include the lower SHA2's.
But since the whole point is for snapcraft to fetch the blob, it seems
trivial for the snapcrafter to use a longer one. It's highly likely they
are cutting and pasting a long string, not typing it in from memory :)
