I find it a bit surprising that there is no option in a browser to stop this kind of behavior. There is even a suggestion on mozzila.org.

With this option placed it would just be another 'fun thing' you don't need to mind.

The cursor icon is useful as an indicator of function - e.g. the "I" styled character over text (where you can select/highlight then copy), and the "hand" icon to indicate a link.

Being able to change the cursor to indicate a behaviour can be beneficial, especially with dynamic DOM elements.

Going rogue with mouse cursor icons is a UX minefield though, and it's usually done without any UX assessment of the impact.

		Ah, yes. I'm sorry. I think i was not precise enough. This is certainly a wanted feature. I meant the ability for a website to change the cursor on its behalf, regardless of elements used or objects on the site. Context sensitive behavior on elements is something that should not be affected with said option.
