> The ultimate question though is, why are these services even separate if they're mutating the same data? Just merge the services (or at least the operation in question) instead of rewriting the entire app.

Because if you did that you'd have a monolith, and microservices are really fashionable right now.

I am not sure if you are being serious or not.

Being fashionable is the worst possible reason for making technology choice, but sadly one which many developers mindlessly choose.

I agree with you, but I am being serious that there are developers stumbling into poor microservice architectures based on "microservices are best practice", ie. fashion.
