### BREAKING CHANGE
#### Datetime, Date and Time fields will always be cast to respective objects in `setattr`, this will ensure uniformity while accessing the values, no more `getdate`, `get_datetime`, `to_timedelta` wrapper.
- While importing data, the framework does check for `set_only_once`.
- In normal case scenarios, this will work flawlessly since most date fields might not be set_only_once.
- But in Subscription, the date field is set to `set_only_once` and in `after_insert`, `document.save` is called, and while doing so, `set_only_once` is checked [here](1944a547f9/frappe/model/document.py (L566)).
-This works fine if the data imported is in the correct format.
- If the date's data is not in the correct format, the framework throws an error.
- for eg `06-02-2022 00:00:00 != 06-02-2022`
- fixes [Issue/#15370](https://github.com/frappe/frappe/issues/15370)

This only affects OAuth clients that use `id_token` obtained from `frappe.integrations.oauth2.get_token`.
Doesn't affect OAuth clients that ignore id_token and explicitly use `frappe.integrations.oauth2.openid_profile` endpoint for getting user details. e.g. Frappe OAuth client.
A simple way to replicate this is to setup Frappe-Frappe OAuth client-server pair and use `login_via_oauth2_id_token` instead of `login_via_oauth2` in `login_via_frappe`.
Each new doc inserts a version, this contains nothing but creator and
creation time.. which is already immutable information on the original
document.
This was added for cases like data import to track from where document
got created, ref: b7dfe7969d
Fix: only add a version on creation IF creation info is present on flags
