This is hand-wavey, but that can't be true: less complex type systems manage to express all kinds of interfaces correctly all the time.
You're asking me to tell on my coworkers, and I'm too loyal to throw them under the bus :)
Well, OK, here's one, but I'll keep it as blameless as possible. We had a thing where we wanted to register some event handlers. The primary use of these event handlers was to run a selector, and if the selected data changed, trigger an update, passing the selected data along. The initial implementation used existential types to store a list of callbacks, each returning different selected data. The "driver" then did the equality checking and update triggering. We later changed this, so that the callbacks - as far as the driver was concerned - all returned `void`, eliminating the need for an existential type. We just had to move the equality checking and update triggering inside the callbacks.
Some features are straightforward translations: anywhere you have overloading and/or optional arguments you can (and often should) simplify by refactoring into multiple functions.
For a concrete, public example...well, I remember the Uppy library had a lot of stuff like this. A lot of work goes into making it's "Plugin" interface look the way it does (start at [1] and keep reading I guess), and while I haven't sat down and re-engineered it I don't think it needs to be this way, if you're willing to give up some of the slickness of the interface.
