It's a neat idea to be sure but I fail to see how this will have any material impact.
Firstly, OpenBSD is a niche OS, meaning the absolute magnitude of OpenBSD cron jobs out "in the wild" is relatively low.
Second, my understanding is that this is a client-side feature. I.e. if I run a service, this feature only benefits me if a significant portion of my users opt into it.
Third, I have an unsubstantiated suspicion that cron usage relative to systemd usage is also on the decline.
