Apologies, but I'm not clear on what the motivation for this change is or what this intends to fix/improve. Is there an issue or could we include a description in the PR?

Most glaring here is the value of the dense rank isn't clear to me (yet). (Also, very sorry for the late review. 🙏)

This PR came about from a one-off conversation between @kasteph and myself. There isn't an issue tracking this, as it's mostly explorative work. The tentative next steps are refactoring the gap-find query into a single SQL function. @kasteph I've converted this to a draft to signal this, hope that's alright with you.
