Hi, I understand your point.

It's not a matter of the select action actually, but rather, the 
programmatic functionality.

The problem that I've been seeing a lot lately, is a widespread assumption 
that the use of ARIA will make something accessible.

This is not actually true; ARIA will enhance accessibility for a control 
that is already accessible, but it can't make something that is not 
accessible, accessible.

For example, in the case of the select controls,

However, literal keyboard focus is not being set on the various list options 
when the keyboard is used to navigate between each select item. You can see 
this by disabling CSS in your browser, then try to set focus on the link 
that activates the drop down, activate it, then try using the arrow keys to 
see where focus is set.

You will see that focus is not actually being moved between the various 
options, making this control impossible to function from the keyboard, and 
impossible to make a selection in the same manner as when you use the mouse 
to click a select item like "West Virginia". If you refrain from using the 
mouse, it won't work.

I've seen this before, where CSS is used to make something appear to be 
happening, but in actuality, nothing is. This causes many problems, because 
nothing that occurs in CSS for simulating the movement of focus is 
accessible from the keyboard, and the use of ARIA in cases such as these, 
only changes the feedback of an inaccessible control for screen reader 
users, but doesn't make it any more accessible.
