I've posted a follow-up to my article last month about SHA-1 chosen prefix
collisions and DNSSEC. This discusses DNSSEC validation:

https://www.dns.cam.ac.uk/news/2020-02-14-sha-mbles.html

Summary:

DNSSEC validators should continue to treat SHA-1 signatures as secure
until DNSSEC signers have had enough time to perform algorithm rollovers
and eliminate SHA-1 from the vast majority of signed zones.
