agreed. on the condition that the community accepts that a broad
tree-wide change (or set of changes) will have to be accepted later
to introduce the abstraction.

communicate that this isn't the only abstraction that will be
introduced to improve portability. there are areas other than atomics
that need to be addressed in the platform/toolchain matrix.
