This is a trimmed-down version of 63d4cae009 that avoids
backporting pain for v11.x. The remainder of the original commit
can be cherry-picked later, once other PRs have been backported first.

--- Original commit message ---
Having an experimental feature behind a flag makes change
if we are expecting significant breaking changes to its API.
Since the Worker API has been essentially stable since
its initial introduction, and no noticeable doubt about
possibly not keeping the feature around has been voiced,
removing the flag and thereby reducing the barrier to experimentation,
and consequently receiving feedback on the implementation,
seems like a good idea.
