&gt; The decisions are being made by the same people who want the company&#x27;s original 1970s COBOL application to keep running until the heat death of the universe.<p>Neither Google nor Mozilla have COBOL applications from the 1970&#x27;s.<p>Given what I&#x27;ve heard from people who work on Chrome say about the people who work on MSFT&#x27;s browser, MSFT has recently <i>also</i> become very interested in making software development for a web browser easier, better, and safer.<p>&gt; The Web has the same problem with ancient deployments that management thinks should just keep working unchanged for decades.<p>We&#x27;re talking about <i>new</i> features marked as <i>experimental</i> and <i>unstable</i> by the folks who <i>write</i> and <i>maintain</i> the browser that <i>implements</i> that feature. As I said in a previous comment, even Microsoft has the backbone to break in-the-field software that makes use of undocumented or experimental APIs.<p>We&#x27;re not talking about changing or removing XMLHttpRequest. We&#x27;re talking about changing or removing blink-experimental-webgl-blink-tag-over-web-rtc-ea59f01.
