The old implementation allowed calling SmallVector constructor and operator= for any type without restrictions, but then failed with a compiler error when the type wasn't a collection. Instead, we should only use it if Container follows a container concept and just not match the constructor otherwise. This fixes an issue @kimishpatel was running into.
