Description
The MVC link builder has some great Kotlin extensions that reduce the boilerplate code quite a lot. But when using reactive, which is quite a valid use case when using Kotlin, there is no such support. Writing model assemblers for both reactive and coroutine controllers is cumbersome.
This pull request would simplify model assemblers in these cases: https://github.com/spring-projects/spring-hateoas/pull/2228.
Here's a sample diff of how I could change an existing reactive model assembler with the PR:
Here's a another example for the introduced coroutine assembler:
Also, in the controller, I do not have to add awaitSingle() after every call of the assembler.

Research direction
Compare the existing MVC Kotlin extensions with the reactive link builders, then review the changes shown in pull request 2228. Done means reactive and coroutine model assemblers have equivalent Kotlin support and controllers no longer need awaitSingle() after each assembler call.
