I still fail to see the point of your approach. It sounds like you're referring to blue/green deployments without using it's name, for some reason, and while failing to present any case of why a monolith provides an advantage. You're just showing downsides without any upside as a tradeoff. I mean, with microservices you can also do blue/green deployments, and they are not all-in like monoliths. Each deployment only covers a subset of features that can gradually be rolled in and out with the only risk of causing partial failures.
