Just a not that there is a way to get a bug report filed - call support, get the issue escalated because its not fixed, if they cant fix it it will go to engineering.

I have personally witnessed hundreds of support cases go through this various process, in some cases taking months of work (for communication mostly from eng to customer) of T2 support reps.

Now - is their current spend sufficient? Probably not, but Apple consistently ranks among the highest customer service ratings - so they probably think spending more here is a waste of time.
