All true about monitoring and logging. Is is a huge cost and overhead. Consider it the other way around: micro-service to monolith. It seems to me it is as difficult, if not more difficult. Potentially different language or different build system are used. Different framework might be in place. Sometimes a merge is completely infeasible without a total rewrite. So going from micro-service to monolith is like going from 3D to VR. Splitting seems in a way way easier than merging back.
