I liked it on an application with a complex conversion flow that could be initiated from a few different starting points with a few required steps and a mix of optional steps that might be executed in different orders. Storing the user's profile data from each step as an event helped us model the whole process as a state machine, which made it easier to reason about this big complex thing, as well as to introspect the previous stages of a user's journey right in the application.
I've also thought it made sense on an application that regularly synced down data from 3rd party systems, where it wasn't uncommon to have some kind of weird data introduced and struggle to reconcile when/where it came from against changes made by application users on our end. Having everything as a series of events can be really awesome in that case.
Im not the OP but I’d chime in: first and foremost it’s on the resume.
Of course im not bashing event sourcing altogether but right now resume boosting seems to be the driving force to apply it everywhere.
And this comes from my experience at my current workplace. Event sourcing has brought so much unnecesary complexity to a an older system and it’s not even implemented properly. The engineers who took the initiative padded their resumes then went on to greener pastures while leaving a giant mess behind.
