I wouldn't say its crucial but I think it would be a nice feature
I'm not convinced
As soon as you introduce alpha month characters into the beginning or middle of a file name, sorting becomes almost random.
The beauty of using yyyy-mm-dd at the front end of a file name is that list of image files are automatically sorted in a logical order. If you had feb, mar etc. instead of 02, 03, the file list would be all over the place.
I recently used Flashpipe to download a couple of years worth of images from my phone camera and used the folder naming of month number - name. In that way I have them all segregated by year and month and images in each folder are in sequence. I didn't need to have the month name in the file name.
