What specifically are you looking forward to?
What I want to see for myself is how Unit compares to those for this reduced scope (api's/services) and how fast I can be productive with it. This could be a good starting point for a lot of new applications, kind of an "airflow (the data orchestration thing) on Webassembly".
So main points are performance (is it good enough) and developer experience (is it easy to maintain/change).
Nothing really ground breaking, just trying out stuff.
