I think that the thing being disputed isn't that ARM is different from 
PCs, but rather the issue that different ARM SOs do the same thing in 
different ways.

in the early days of the PC we had the same issues (those who were around 
to remember the 'almost' PC compatible machines (from some of the biggest 
names in the business). they all thought that they had good reasons to do 
things differently, but over time they all changed to hide the differences 
from the system.

ARM is currently in worse shape than the PC market ever was in this 
aspect, but in this case it's less a matter of getting the hardware guys 
to change what they do than it is to get better documentation of what the 
hardware is really doing and not duplicating drivers for cases where the 
right answer is just replacing a constant with a variable (just as an 
example of the very common case where the same component is wired to a 
different address)
