I have started a package that defines org-capture datetrees following year-quarter-week and year-month-week formats:
https://gitlab.com/jackkamm/org-grouped-weektree I'd appreciate feedback on 2 points: 1. Are any of these datetree formats worth upstreaming into org-mode proper? 2. Can we add a public interface for `org-datetree--find-create', and are there any suggestions on how to do it? Regarding #2, an ugly aspect of my current implementation is the abuse of the private function `org-datetree--find-create'. I also pass in the week or quarter for the DAY and MONTH arguments of this function, though I note that `org-datetree-find-iso-week-create' does something similar in its implementation.
