[Discuss] Best-practice to prefer lists over arrays in any form

This recommendation is a natural extension over "avoid varargs".

There are enough arguments for that (mutability, covariance, no compile-time safety).
The question is whether it is applicable enough to be included into API guidelines or should be a part of something like "Effective Kotlin instead"

Start with the issue's arguments about mutability, covariance, and compile-time safety, then review the existing guidance around “avoid varargs.” Determine whether preferring lists over arrays belongs in the API guidelines or in something like Effective Kotlin; done means a decided placement and documented recommendation.
