This is why you ALWAYS have a proposal ready. I literally had my ass saved by having tickets with reliability/redundancy work clearly laid out with comments by out of touch product/people managers deprioritizing the work after attempts to pull it off the backlog (in one infamous case for a notoriously poorly conceived and expensive failure of a project that haunted us again with lost opportunity cost).

The hilarious part of the whole story is that the same PMs and product managers were (and I cannot overemphasize this enough) absolutely militant orthodox agile practitioners with jira.
