Yes, but it is comparatively easier getting say, the result of an API's GET and pasting into a file as a sample, than manually tweaking types. At least when you're starting out or if it's a small F# program. You could even use the actual network path, but that's a bit... wilder in terms of maintenance/reproducibility.
Plus, since you can have arbitrary providers, such as a provider that connects to a DB and generates a type-safe "ORM" over your relational database[0] with no configuration other than pointing to the data source you're going to access at runtime. Perfect if you want to write little data transformation scripts.
