How about we stay away from nonsensical conclusions.
Nobody is saying support for existing formats should be removed. Really the only reason people are voicing a different opinion is probably because they (I at least) think development cycles could be used better than developing support for a native recording format that most people don’t use. I for one would like to see Steinberg spend WAY more time dealing with what actually gives us the media to work on to begin with; aaf/omf exchange. I can’t think of many issues that are of higher importance than this for a post-production DAW. And I think other people feel similarly; better to spend the time on certain things than others.
