MinValueValidator with localized date format message

Using Django Using the ORM
1

We have several locales and we want to add a MinValueValidator for a date. We noticed that the error message is in the correct language, but the date format is not.

Example model:

Class Report(models.Model):
    start = models.DateField(
        verbose_name=_("Start Date"),
        blank=True,
        null=True,
        default=None,
        validators=[MinValueValidator(date(2020, 1, 1))],
    )

Example outout:
Dieser Wert muss größer oder gleich 2020-01-01 sein.

The expected date format for the German locale would be: 01.01.2020.

When checking the BaseValidator class, one can see that it simply passes the limit_value but does not localize it.

So the question is:
a) am I doing something wrong here?
b) could this be a feature request for django itself?

I’m aware, that I can override the validator class and localize it or pass a custom message.
But I think it could improve the localization of django websites if it a) automatically localize the value when outputting the message or b) there could be a localize parameter (similar to the form field localize parameter

This does sound like something where django.utils.formats.localize could or should be used.

Here’s the ticket where this was reported before: #33112 (BaseValidator does not localize params passed to rendered ValidationError) – Django but this seemingly didn’t go anywhere because nobody followed up on it until now. (The change hasn’t been rejected by the way! It was a request for more information about it.)
