It seems the only reason given is "some clients are broken"? They mention latency but I wonder what the real world impact is. On a home network, most users are using ISP supplied DNS which /usually/ has pretty low latency and will have a huge cache already built up. Corporate users will have DNS cached to all the common host they're visiting. Anecdotally, AWS ALBs (HTTP load balancers) have a CNAME with a 10 minute TTL (maybe it is 60 seconds) and can have their IPs change 100s of times a month and this works fine as a default configuration for many use cases.
