It&#x27;s cute, because the dedication to backwards compatibility is so uniquely Microsoftian: &quot;We&#x27;re going to create this API that idiots will inevitably abuse or misuse. Then, in the next version, after all the idiots have abused or misused the API, we&#x27;re going to deliberately return wrong results from it so that the idiots&#x27; applications don&#x27;t all break.&quot; It&#x27;s really baked into their DNA, all the way back to the early days of Windows where they replicated all those DOS bugs so buggy games that took advantage of them would still function on Windows.
