Custom runtimes with Kotlin/Native
While Ktor doesn't support Kotlin/Native yet maybe the Kotless DSL can be ported. I do believe it will reduce cold boot times and costs, maybe even functions will run faster. Maybe I can give it a shot in my spare time but first I'd like to hear your thoughts. Are you interested in support for custom runtimes in Kotless? Would you consider merging such a pull request from the community? If so I would love to hear about the preferred approach to tackle this issue.

Hey, kotless 0.1.7-beta-4 supports GraavVM Custom Runtime. Does it solve your problem?
I also want to note, the feature is being tested right now.
GraalVM is still a VM (or at least I hope so cause it's in its name). For optimal performance it will be best to ship nothing but a runtime by compiling to native.
GraalVM is a VM only during compilation to native binary. The result product is a native binary :)
I will try to pull out some measurements between a Kotlin/Native binary and a GraalVM binary then to see if it makes sense at the end of the day. :)
Here's a reason not to use GraalVM. It is GPL licensed.
As far as I understand, code generated by GraalVM would not be GPL licensed. So, it should not be a problem.
