Are there any idioms for API versioning with ktor? I haven't found much searching around, pretty much just this gist:
https://gist.github.com/felix19350/1acb1c69102f5880ce0440f058f2352f . I know I can just do something URL-based, but wondering if ktor has any features that work well for this (like the content-method in the gist, for example, which I wouldn't have thought of)
