Comment 2 for bug 201711

As commented on by mjg:

My experience is that the majority of users who run Linux on Apple
hardware are also used to MacOS, and so maintaining consistency with it
is worthwhile. That's entirely independent of the fact that altering
this in the kernel would change the default behaviour of the system for
users who are upgrading, which would be highly confusing.

Apple hardware tends to be intrinsically different to other PC hardware,
and we're limited in our abilities to make it behave identically - the
glaring lack of more than one mouse button is an obvious example of
this.
