[5.x]: Field postDate and expiryDate can't be made visible for entries

What happened?

Description

Not sure if this is supposed to be a bug or a feature request.

In CraftCMS 5 entry types are stored in the entries table.
Therefore they also have the fields postDate and expiryDate.

By manually setting an old date to an entry via the database it disappears from the frontend output.
Therefore the logic is already implemented.

But there is no way to make the fields visible in the backend expect by creating a section for it.
Also by opening the entry with the edit view, the fields are not shown.

Solutions

the fields should be visible globally or optionally at an entry level with a toggle.
This could be also added to the dropdown menu for matrix table
ex:

Benefit

Entries can in addition of being disabled, also be scheduled or hidden in the future identical to sections.

The issue names no files, tests, or entry points. Start by clarifying whether postDate and expiryDate should be globally visible or configurable per entry, then define the expected editing and scheduling behavior; done should cover an agreed backend UI and frontend visibility behavior.
