While a namespace is locked to only be read by a group of users ([[Extension:Lockdown]]), creating pages in such namespaces will lead to a auto-summary including a part (or all) of the page content, which is not expected as the namespace is designed as private.

However, disabling auto-summary across the whole wiki makes other public namespaces unable to benefit from the auto-summary feature.

Therefore, I hope there can be a config to disable autosummary per namespace.

Not sure if this is a intended design or a bug. If this is intended, just abandon the patch.
