IF you go through a vetting process like we do, it takes a while to vett changes.  We can't just jump to new firmware just so they will do the support we paid them for.  

When they come to give you the dog-and-pony show, that's when I jump in and ask for things.  They are here to solve your problems-that's the first thing they will tell you.  If they help you succeed, you will stay in bed with them. That's a win-win situation.  

A node on a pallet waiting for you do upgrade firmware is absolutely worthless.  1000 of them even more so.
