For date fields, it will be useful to get the format in line with the users locale or region. Especially, when the tenant is a multi-national enterprise, users should see dates in a format they are familiar with. For example UK user see "dd/mm/yyyy" and USA users see "mm/dd/yyyy".
Another quick fix may be a global setting for an app to set the format instead of setting it for each date control. This will not address multi-nationals, but at least make developemnt easy for single country tenant.
Since default is "mm/dd/yyyy" the developer has to remember to set format for each date control in other regions.
