Yeah, you're right I did judge. Sorry. I don't know your codebase, I just find it odd that a single variable would exist across 78 files. Feels wrong to me. Something like KISS or maybe SRP come to mind. But again I don't know your codebase.

I think what they were doing is renaming a key in an interface, like going from to data.isOnline

Or adding data.timestamp. With TS you automatically get notified of all the places where this data has to be set and also you now automatically know everywhere you use data that it also has a timestamp property. Also, TS ecosystem goes further than that, you could have Protobuf definitions that might be updated because data is serialized and sent over the network to multiple other services, and with the updated TS typings everyone just knows about this change and can update their code accordingly. And yes, this data interface could be used by hundreds of files across multiple services and git repos.
