the spec says:

"User agents are required to implement ARIA semantics on all HTML elements, as
defined in the ARIA specifications. The implicit ARIA semantics defined below
must be recognized by implementations."

Unless its explicitly stated the user agents must not map <img alt="some text">
to a graphic role in an accessibility API they can can continue to do so and be
conforming to the spec.

I am not disagreeing that the editor intent or desire is to forbid user agents
from mapping an <img alt="some text"> to a graphic role in platform
accessibility APIs, but unless it is specified, it is not correct to say that
user agents need to do it, it is not up to anybody to try to divine what the
editor has specified by omission.
