I suspect ARM's business model - dependent wholly on licensing the ARM
architecture in various forms - would make it very difficult for them
to agree to that argument even if it would gain them one customer.
It'll be interesting when someone develops a compiler that uses very
detailed machine descriptions - with enough detail to describe an
architecture well enough that the description can also be used (by a
different program) to emulate it to a significant degree.
They need good compilers to support the architrecture. But a very
detailed machine description is also their business nightmare: the
basis for software, and later hardware, implementations of their
architecture. I wonder if people such as yourself will be able to
contribute to the development of the machine description for such a
compiler.
