## Summary
Concurrent rendering has been the default since React 18 release.
ReactTestRenderer requires passing `{unstable_isConcurrent: true}` to
match this behavior, which means by default tests written with RTR use a
different rendering method than the code they test.
Eventually, RTR should only use ConcurrentRoot. As a first step, let's
add a version of the concurrent option that isn't marked unstable. Next
we will follow up with removing the unstable option when it is safe to
merge.

if our app is still using the legacy root to render |

@jackpope regarding
since react18 still allow legacy root by ReactDOM.render, it is still possible to render in non concurrent mode in 18, what would be the plan to keep backward compatibility in RTR? |

Reverting some of #27804 which renamed this option to stable. This PR just replaces internal usage to make upcoming PRs cleaner. Keeping isConcurrent unstable for the next major release in order to enable a broader deprecation of RTR and be consistent with concurrent rendering everywhere for next major. (#28498) - Next major will use concurrent root - The old behavior (legacy root by default, concurrent root with unstable option) will be preserved for React Native until new architecture is fully shipped. - Flag and legacy root usage can be removed after RN dependency is unblocked without an additional breaking change

Reverting some of react/react#27804 which renamed this option to stable. This PR just replaces internal usage to make upcoming PRs cleaner. Keeping isConcurrent unstable for the next major release in order to enable a broader deprecation of RTR and be consistent with concurrent rendering everywhere for next major. (react/react#28498) - Next major will use concurrent root - The old behavior (legacy root by default, concurrent root with unstable option) will be preserved for React Native until new architecture is fully shipped. - Flag and legacy root usage can be removed after RN dependency is unblocked without an additional breaking change DiffTrain build for commit react/react@3832730.

Summary
Concurrent rendering has been the default since React 18 release. ReactTestRenderer requires passing
{unstable_isConcurrent: true}to match this behavior, which means by default tests written with RTR use a different rendering method than the code they test.Eventually, RTR should only use ConcurrentRoot. As a first step, let's add a version of the concurrent option that isn't marked unstable. Next we will follow up with removing the unstable option when it is safe to merge.
