Comment (by Michael):
Sure I will create a patch, before I submit it, would you please review
the following, because I am not 100% sure I understand how the readonly

{{{
You can also override ``empty_value_display`` for all admin pages with
:attr:`AdminSite.empty_value_display`, or for specific fields like
this::
from django.contrib import admin
class AuthorAdmin(admin.ModelAdmin):
fields = ('name', 'title', 'view_birth_date')
@admin.display(empty_value='???')
def view_birth_date(self, obj):
return obj.birth_date
}}}

{{{
You can also override ``empty_value_display`` for all admin pages with
:attr:`AdminSite.empty_value_display`.
To override just a specific ``list_display`` field, or one of the
``readonly_fields``, one can do so like this::
from django.contrib import admin
class AuthorAdmin(admin.ModelAdmin):
list_display = ('name', 'title', 'view_birth_date')
readonly_fields = ('view_birth_date', )
fields = ('name', 'title', 'view_birth_date')
@admin.display(empty_value='???')
def view_birth_date(self, obj):
return obj.birth_date
}}}
