This is a question for any Apple engineer who is able to answer it.
The UITableViewDiffableDataSource class exposes UITableViewDataSource's tableView(_:titleForHeaderInSection:) method which allows us to specify the title of a given section but it does not expose UITableViewDataSource's tableView(_:viewForHeaderInSection:) method which allows to give a custom look to the section header.
Are there any plans for UITableViewDiffableDataSource to expose UITableViewDataSource's tableView(_:viewForHeaderInSection:) method or an alternative method which will allow us to customise section headers in UITableViews?
(I am targeting iOS 13.4 and developing in Xcode 11.4.1 for what it's worth.)
