FWIW, the threat model of digest algorithms being published on an HTTPS
website that then links to the file to be downloaded is much easier to
work around than by compromising SHA-1's preimage resistance (or even
collision resistance for that matter).
However, it makes more sense to me to just move everything to sha-256
today. Anyone who actually checks the digests should be capable of
using sha256 today, and it would avoid this sort of question coming up
in the future.
