I was arguing the opposite, coordinated deployments already presumes more maturity than I was considering. I've only been at one company with same-day deployments. All the other places have been free-for-alls where each group determines their own release schedule, with their own pipelines. Managing deployments between dependent services thus requires significant coordination overhead (or none, because you are stuck with what you get until the other teams deliver your needs on their own timeline). In chaotic environments like that, microservices help with defining clear ownership of operational responsibility, though at the cost of clear responsibility for the overall distributed system. This comes at the cost of making it hard to develop, let alone ship, changes that impact multiple microservices (outside the scope of a single team, or closely related sibling teams). The main point I was making was that, with a more monolithic system, managing that kind to organization disfunction, necessitates top-down, waterfall like control. So moving to microservices enables non-coordinated agility removing one layer of coordination problem (a the cost of other problems).
