Unless the problem lies in an interface shared across many or all services, or the assumed data model, or other higher level considerations. There are certainly monoliths that are successfully being developed on by many people at the same time (OS kernels for example), and I can see a few arguments why developing and debugging with microservices can be harder. For once, it's much easier to deal with most of your state in one address space instead of multiple.
