I disagree. Bowing down to the whims and fancies of corporations is how we got into this situation (in terms of media formats) in the first place. According to wikipedia, HEIC isn't even supported in any browser natively, clearly rolling it out this soon was a bad idea.
Media format support will always be a chicken and egg problem. You got to start somewhere. Apple's approach of automatically converting images at the edges is the right way to go. It does require your software to be explicit about what media formats it understands. This is where the College Board failed.
Funny thing to say in support of Apple. Maybe they should support WEBPs/WEBMs instead?
