Indeed, but is a cron job really a method to confirm continued
acceptance of a service? It requires credentials to make a DNS
change and in a way only weakens the security model. (just like ACME
using DNS-01 doesn't add anything to just publishing TLSA records in
the DNS)

Well, it does show that someone or something is awake enough to run the cron job while I know from personal experience that TLSA records can go stale for quite a while. But we're all waving our hands here.
