Thank you for the kind words about Serverless Stack. Frank and I poured ourselves into creating it. So it makes me really happy when I hear that it ended up being helpful.
On the Lambdas per service front, the express server inside a Lambda function does work. A lot of our customers (and Seed itself) have APIs that need to have lower response times. And individually packaging them using Webpack or esbuild ends being the best way to do it. So you'll split each endpoint into a Lambda.
I just think the build systems shouldn't limit the architectural choices.
