@Adam Eastbury , Thanks for your interest in Azure Static Web Apps service and posting this great question!
The quota remains 10 for the Free tier, but no limit for the new Standard tier. I have relayed this feedback to our product engineering and the content team, we have raised a PR on this doc (Quotas in Azure Static Web Apps), and the changes would reflect shortly.
Also, our content team is planning to publish an article focusing mainly on the Azure Static Web Apps hosting options (with detailed info on the feature tiers/pricing plans). However, there is no ETA to share at this time. Once published, I'll also update this thread.
Thanks again for bringing this to our attention! We appreciate your valuable feedback on this.
