Recognition of a special platform isn't "full support", just addition of 
recognition making possible partial support for special cases. Unless that 
makes for some horrendous recognition decision tree somewhere I would have 
thought that's a pretty low bar to accept, and worth doing.

Leaving aside any bug actually fixed, it makes it much easier for someone else 
to fix a platform specific bug by making a test constant available for turning 
on whatever special mode/code is wanted.

More context on the example patch that triggered this query?
