-The entries with ``*`` in the ``Providers`` column indicate that one or more

+The entries with ``*`` in the ``Providers`` column indicate that one or more
provider packages will be

For ``provider`` extras - they usually install single ``provider`` package,
but for extras that are groups
of other extras (for example ``all`` or ``devel_all`` or ``all_dbs``) there
might be more than one provider
installed together with the extra.
The entries with ``*`` in the ``Preinstalled`` column indicate that those
extras (with providers) are always
-pre-installed when Airflow is installed. In this case dependencies are
reverted - the ``apache-airflow``
-package depends on the corresponding providers packages. This is in order to
avoid circular dependency that
-can be reported by some tools (even if it is harmless).

Review comment:
No neeed. Only the 4 `provider` packages are pre-installed. All others
have to be explicitly added
