I dig Astro and use it to build my blog and several other tiny mostly-static sites. I'm not sure that the hosted database service fills a need I have but, in general, supported SQL integration seems like a useful addition.

As an aside: there are days when I wish I could avoid using the Astro component model entirely, do everything in Preact (or whatever), and still use the `client:*` directives when appropriate. I realize this is easier said than done and also probably not a reasonable thing for Astro itself to try and target -- but moving between Astro components and framework components always has just enough friction that it's something I think I'd enjoy using.
