Missing plone.versioning behavior for Pages

[mliebischer]

Hello everyone, is it intended that the plone.versioning behavior is disabled by default after installing plone.volto for Pages? In Plone Classic, Pages have that behavior enabled by default. Other types such as Events do not appear to be affected.

Looks like a bug to me. If so, it might be better to selectively disable or enable the required behaviors via a setup handler in plone.volto to avoid repeating the behaviors and unintentionally omitting some default behaviors in the future.
