Interesting, hadn't seen that yet; thanks for sharing. Does look like it'll have some nice design concepts -- I've definitely come to view Django/DRF's strong coupling to the ORM as a hinderance to architectural flexibility/sanity as my application has grown.
Interestingly it eschews Swagger/OpenAPI in favour of JSON Schema, wonder how that'll pan out; I like the promise of codegen that swagger offers, but haven't found the generated clients to be particularly usable.
