plone.synchronize is missing, in the default Plone6 Installation the import is broken

[1letter]

Whats the preferred way?

plone.synchronize should added to setup.py in the 'install_requires' - section

or

alternative an import from plone.dexterity >= 2.10.5

[yurj]

try:
    # Plone 6
    from plone.dexterity.synchronize import synchronized
except ImportError:
    # Plone 5
    from plone.syncronize.decorator import synchronized
