Many users would prefer to not have to use their mouse when entering data. This makes their job much more efficient when they can keep their hands in one place. I would expect to be able to type "05/22/2020" and also "05222020" into the datepicker but it keeps getting stuck on the day part. If you look at the demo for MVC, when you type those values, it accepts them but the demo for the Blazor datepicker does not.
ADMIN EDIT:
The MVC date picker does not have the described behavior. By default it is a simple <input> without validation so it will take any input, but typing in the numbers in sequence like that won't select a date. See the rest of the discussion and the updated title for more details on the behavior and issue this will fix.

To reproduce, go to https://demos.telerik.com/blazor-ui/datepicker/overview and tab into the datepicker input. Try typing "05/22/2020" and you will get a result of "5/20/yyyy" because it gets stuck on the dd section.
To see the expected functionality, go to the MVC demo site (https://demos.telerik.com/aspnet-mvc/datepicker) and tab into the datepicker. Try typing "05/22/2020" and you will get a value of "05/22/2020" which is what it should be.
This should work when typing both "05/22/2020" and "05222020" since users will be even more efficient if they don't need to type the /.
