INHO, it's also still sensible to use SHA1 (or even MD5) as a "technical" checksum to protect against problems like transmission errors, storage failure, random bit flips or accidental changing of pristine copies. It's just that we must not use SHA1 as a sole means of identifying content or content identity.
