Right now one can run ionic serve or npm run build (undocumented) to get a simple build from /src to /www. From what I understand, /www is expected to be used if one wants to create a PWA or webserver hosted version of an Ionic app - which more and more people tend to do.
Wouldn't it be great, now that ionic build is not hijacked by ionic cordova build any more, to add and fully document this command to the CLI?
