In reply to Phil Johnston.

It depends on the use case. Generally speaking, I would rather store my testimonials elsewhere and query them as needed. However, there are plenty of use cases where a one-off testimonial pattern would be fine. Think, something like a book landing page where the user will only ever want to show a testimonial on that particular page.

The current patterns are experimental. There are no indications of what will ship when they land in core. But, I could see some type of testimonial pattern making the cut.
