I wish more people would actually use this to wrap their 5'000 lines of console output that they copy paste into a ticket when reporting a bug instead of using markdown "format as code"

Also yes it is a "hack" and not official markdown, but for the use case I mention it has the huge advantage to not make tickets including all the comments excessively long

HTML blocks are part of the commonmark spec. The overlap between people who post too much in issues and know this feature is probably small though. Other platforms have JS that detects long code blocks and collapse all but the first few lines by default.
