"Obviously"
There are plenty of use cases where the filename is relevant (and many, many people intentionally use the image name for sorting / cataloging).
I have had more cases where I was very surprised that the local filename I used for something became part of its record when I uploaded it somewhere. (For instance, uploading an Mp3 using Discord on desktop web.)
There are many, many more cases where the user doesn’t expect the name to become public when he sends a photo. If I send you a photo of a friend that doesn’t mean I want you to know his name (which is the name I gave the file when I saved it)
So in webmail, when you upload an image / file to attach it to an email, you expect it to be renamed? I don't.
I email images as attachments very, very frequently. I go through the browser's file picker and I pick out the photo by its filename. I would be surprised and angry if somewhere along the way the filename got changed to some random string without my knowledge and consent.
In fact, I often refer to the name of the photo in the body of the email (e.g., "front_before.jpg shows the front of the car when I picked it up, front_after.jpg shows it after the accident.")
I imagine this is an extremely common use case.
