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.

They don't appear to document this, save that they handle 10k QPS read or 2k QPS write and can deal with 2TiB of data. They also recommend that you have 3 of them:

For me, this immediately discounts it:
> $0.90 per node per hr
That's $648/mo in pure overhead.
I'm not saying there should be no overhead but it shouldn't be that high.
They also optimistically encourage you to try it with a "free" trial. The "free" trial, assuming you haven't used GCP before, gives you $300 credit, which is enough for less than 2 weeks of a single Spanner node.
Plus according to https://cloud.google.com/spanner/docs/instance-configuration, they recommend a minimum of 3 nodes, or $1800/mo.
I know this is targeted at businesses but it'd be nice if we could get smaller "nodes" or something to lower the barrier to entry. You shouldn't have to go straight from nothing to 10k QPS.
And that's fair enough, I understand dedicated/shared are very different things, it's just that for me, right now, Spanner isn't viable. Change that and you'll be a whole lot more appealing!
