The function keys which do something in minecraft (F1, F2, F3, F5, F8, and F11) can't have their key bindings changed.

Other reports of Mojang forgetting to add some instances of something when all the other ones were included, like MC-47832, have been accepted as bugs. Why not this one?
The difference in this case is that, though there isn't the option to change the keybinding, current keybindings exist. The example you give is more a missing game mechanic, which could prevent proper functionality of certain commands. Here, the keys function, it's just a matter of whether or not you can change them.
In MC-47832, most entities could be selected, but a few couldn't. In this ticket, most keys can have their bindings changed, but a few can't. In both cases, Mojang added some functionality to the game, but excluded a few instances of that function.
