> Google Docs is not a tool for accomplishing a task that used to be (and to some extent still is) considered a lifelong learning experience requiring significant skill (audio engineering)

I would argue that the lifelong learning experience has more to do with developing a good ear (and taste) than learning specific technical tools or workflows. Anything that helps experienced audio engineers collaborate with talented musicians and composers working from home is a good thing.

With regards to plugin APIs, hopefully the web-DAW community can agree on a de-facto standard based around WebAssembly, and ideally that standard would be fully open. If it is successful, the native DAWs have the option of supporting it too.
