Why don't mirrorless cameras have a 'shutter down' function?

I would much rather have something get on the cleanable glass surface in front of the sensor than on the shutter mechanism itself. It's easy to clean the glass. It's not easy to clean the shutter mechanism without doing damage.

This is such non-R6/R5-owner cope. You don’t have to clean the shutter, ever. What are you even smoking? But obviously sensors do need to be cleaned occasionally. We all know that. When they get dusty, you get black specks on the image. Of course it makes sense to have a sealed barrier in between the outside world and the sensor when changing lenses.

I believe he is trying to say that the sensor's cover glass is much easier to clean than the shutter blades, if debris get on them. With the shutter exposed, there is a larger chance of getting debris on the blades and those debris may damage the blades as they go through their cycle. Those blades are extremely thin and have a very delicate coating of them. I have to agree that having the blades exposed is not the best idea and having another set of shutters just to protect the sensor during lens changes is overkill.

We can all cite thousands of examples of dusty sensors being a problem. Just look for dust spots on any photo taken with a camera that is not brand new. Can you cite any example of a "dusty shutter" being a problem for any camera? It just seems like a coping strategy for people whose mirrorless cameras display the sensor bare when the lens is removed.
