I consult across a few different industries, but it includes SaaS offerings. Many places could do multiple deploys to prod a day, but choose weekly releases or other longer cadences. This is to allow for documentation, client notifications, etc. It also is more efficient, constantly releasing requires a lot of resources, as this blog implies they are churning dozens of K8 pods several times a day.

I would think constant releasing would also make debugging prod issues pure hell.
