Not an unjustified prejudice, but an unjustified spending of resources, when such resources are not always readily available.

It's like creating a really nice set of Christmas lights, which only comes with a complete car as a part of the package, because it's powered by the car's engine. Indeed, a car's engine is a really good, well-engineered engine, and it works everywhere. But often one would really appreciate a string of Christmas lights that works from a wall power socket, and is 1000x lighter.

I find Kando a brilliant prototype of a future useful tool, which would have the size, complexity, and attack surface commensurate with the functions it provides.

I want to use something like Kando, but probably not Kando directly yet. I also suppose that Kando's approach, and most of the code, can be reused in proper web apps.
