Yes, there are numerous other ways to run remote commands than ssh, all of them less secure. (Running commands via your monitoring system can even be a very handy back door in a pinch.)
The argument here was that remote commands was less useful at scale, not that ssh was a particularly bad way of implementing it. Which doesn't make sense. You tend to have more complex system interactions at scale, not less.
