DATE and DATETIME settings have no effect since USE_L10N was deprecated

[Paul]

Since 5.0 USE_L10N settings was DEPRECATED and is always True.

Now settings like DATE_FORMAT, DATETIME_FORMAT, DATE_FORMAT_INPUTS etc.. don't work because as per documentation:
"Note that the locale-dictated format has higher precedence and will be applied instead. But now locale-dictated formats are always enabled."
Now locale-dictated formats will always have higher precedence.

It alse breaks editing on all ModelForms which have date and datetime fields because the input is expecting ISO format, but Django forcefully localizes the value attribute to another format.

I've found a solution but overriding the formats.py file using the FORMAT_MODULE_PATH setting. I think at least the documents should make it clear you can do that.

I don't think that it's true, can you provide a sample project that reproduces your issue.

True, if you don't like formats provided for a language you're working with, you can use FORMAT_MODULE_PATH to specify your own format definitions. This setting is documented, I'm not sure what else are you trying to propose.

I've created a demo project at ​https://github.com/paulik123/django-demo-l10n
Just create a demo object then click edit.

Yes, but not specifying that all format settings (DATE_FORMAT, DATETIME_FORMAT etc) won't work if you just paste them settings.py seems confusing to me. I think at least a note should be added saying that to modify these settings you need to override formats.py

I missed this ticket yesterday when triaging #35306 but I think they are the same issue (documentation could benefit from some explicitness).
