Rick:

I appreciate your passing along the knowledge... however I'm going to politely disagree with you.

As someone that has written a line or two of code for a living I can say that this type of decision tree isn't particularly difficult to code in the software. Assuming that the mothership has figured out how to either code a definitive hardware model and/or a serial number into a location that is programatically addressable it's childs play. We'll assume it's serial number and that serial number X of the product is the first serial of the new hardware type.

Here's what it would look like in pseudocode
set version=v1.09

if serial < X
set version=v1.08
endif

install version

Want to make it easier for later releases, give them the same base version numbers (such as v1.08) and append an A for baseline hardware and B for second rev of hardware. This becomes extensible through many versions of hardware.

The real world code would be a bit more complex depending on language etc, but not unduly so.

I also respect that the mothership is well within their rights to change their business model. I can't say that I am pleased, but I'm okay with that.

But the ability to programmatically resolve the versioning quandary on the HD621 makes your argument not a particularly robust one.
