Exciting initiative!

I think this line in Update is "orphaned":

set myobj = ##class(%Library.DynamicObject).%FromJSON(%request.Content)  

@Justin Millette, there are more settings to enable in the system to allow delegated access, e.g. a system-wide setting, mentioned in this great @Pravin.Barton's article , also there is another one from @Yuri Marx 
 

Also, I don't recommend using the WebApplication tag as it is not working properly yet; there is at least one important bug not solved: for example , CSPApplication works quite well. 

Also, I see %all - I hope this is for development/demo usage only, as it is quite a generous role to use.

Great stuff!

Made an example in ObjectScript Docker template:

@Thomas Wuppermann, you can add an env variable in docker-compose.yml to make merge cpf be implied, and the merge.cpf with the name you prefer.
