Just coming here to voice my agreement that these warnings are annoying and exist in other libraries as well. For me this happened with svelma. I didn't write the library code, so I don't have complete control over it even though I agree there is an argument to be had around whether I should be notified anyway. In either case, these warnings should be easily disabled since libraries don't always get updated over night.

// `lodash/padStart` accepts an optional `chars` param. _.padStart('a', 3, '-') // ➜ '--a' // `lodash/fp/padStart` does not. fp.padStart(3)('a'); // ➜ ' a'

I prefer to have optionality over compound planing (assumptions, based on assumptions, …).
