Thank you for finding this.
It is actually the the goal of doing this exercise to find the places where we think we should support unitful behavior but do not.
I have opened #27500 to track the underlying problem.
I will block merging this until the underlying problems are addressed.
PR summary
I've created a test for Axes.streamplot in test_datetime.py as requested in #26864
I tried using the normal datetime.datetime data type and passing that into np.meshgrid. However, it looks like np.meshgrid doesn't accept the datetime type and only accepts numerical arrays. I tried doing some research and looking into np.meshgrid further but could not find any way to pass in an array of datetime values. Therefore, I had to convert the datetime values into numerical values using date2num. This allows it to be passed into np.meshgrid to create the X and Y arrays which are then passed into the streamplot function.
Note: I am new to working with matplotlib and also new to open-source contributions so I would really appreciate your support and advice on this PR.
