Agreed. I have worked at a Fortune 100 firm where its business ran (still runs) off of an ERP sharded into 100 instances, each representing one key facility since the mid-90s. It took extra work in the early days to centralize analytics and manage deployments and data, but it has been very resilient (low blast radius in today's terminology) and natural for low risk deployments, rolling out of upgrades to one site, then the rest in batches.
