Google Maps is one of a tiny, tiny set of still-relevant products that still support their decade-old interface. You never stated you were referring to ONLY public web apis. In fact you simply said "Apps". But even if you really meant only public web apis there is precedent (Google's many APIs) where APIs will continue years and sometimes even decades. Is it unlikely? Probably, depending on what you're doing, but certainly not impossible nor "insane". As a software developer who's seen web apps function for a decade + with little to no changes (one of which actually did rely on a third party API) I fail to see how anything I stated was "insane". Not everything has to have major breakages every 6 months.
