Entry ordering - any interest?

I'd be happy to write a PR that makes entries on the collection page draggable if there is an "order" field on that collection, and the order of the dragged elements would be reflected in said field.

This would allow most CMSs to then order entries by that order value and thus give us custom ordering.

Would such a feature likely be accepted?

No files, tests, or entry points are named. Start by locating the collection page and how collection configuration exposes an order field, then confirm the drag-and-drop and persistence expectations with maintainers; done means entries can be reordered and that order is reflected in the configured field.
