The challenges are designed for an average engineer at the job opening level (junior, mid, senior) to solve in approximately 10 minutes. Furthermore, they are practical day-to-day tasks that should not put pressure just by nature of what's being asked.
For your last point, a review takes on average 5 minutes for a hiring manager. And I think screening more is not inherently a problem. Imagine they turned down the dial on their CV filters and had more applicants do a technical screen - wouldn't that give more applicants an opportunity to shine? In most cases it unfortunately is a numbers game.
