I don't know where the $9/month number comes from but as someone else said, I edited my post (added a bunch of things) so maybe I edited out something that could be read that way.
Basically yes, I'd like a shared Spanner. If $648/mo gets you 10k read/2k write, then for ~$9/mo you should be able to get roughly 140 qps read and 9 qps write, so long as cost scales roughly linearly. Assuming you can spread this over the month (1000qps here, 0qps there), this would be super appealing to a lot of smaller projects I think.
I think the way it is, it's exclusively a business tool but it has potential to be so much more. Imagine if it was possible for anyone to set up a distributed, fault tolerant, scalable Wordpress instance using Cloud Spanner, Cloud Functions and Cloud CDN any pay per uncached pageload? You could even set it up with a single click in the Cloud Console. Running your own scalable cloud service would be no more difficult than setting up a Tumblr blog.
