Did you plan to land this change or is this more of an experiment to see if we could get rid of paginated_multicolumn? FWIW #7717 makes sense to me because we didn't have a way to do that and I agree that expanding this family of functions sounds...awful. I'm less sure it's worth getting rid of paginated_multicolumn given that we have it.

It's a little bit of both - I wanted to see what this change would look like more broadly, and also wanted to measure at some point to see the impact on compile time, since paginated_multicolumn has fairly complex trait bounds.
