Drupal events content type next generation

Problem/Motivation

We are currently collecting ideas and features, which should help to rethink the drupal.org events node type.
there is a first draft of a document here: https://docs.google.com/document/d/1Hc_HXl3ZH4MaiKILD5oA7qpwj156QHy8FZwW... let's collect details first there.
…and the plan to setup a monthly meeting to clarify/prioritize the wishes and ideas (finding the right time here: https://doodle.acolono.me/invite/bS7GiqRuqnei)
