SE conferences have an interesting journal-first presentation model. For example, papers accepted to the IEEE TSE journal can be submitted for presentation at either ICSE, FSE, or ASE the same year. Conference can be chosen based on travel cost (money or carbon) and visa issues.https://twitter.com/vj_chidambaram/status/1205545163935899648 …
I believe review of journal-first papers is also lightweight, since they are already accepted by journal reviewers. See https://conf.researchr.org/track/icse-2020/icse-2020-Journal-First#Call-for-Contributions … for ICSE 2020's call for journal-first papers.
