I am not saying this **exact** feature is needed by Wine. What I am doing is a 
parallel with `__attribute__((ms_abi))`, which is exactly the same as this 
exact feature, but to target the MS ABI from a foreign OS (instead of the 
Darwin one). Wine just can't work without that attribute.

Let's imagine that, at the time people had wanted to introduce 
`__attribute__((ms_abi))`, we would have told them "this is a niche, hack 
<insert compiler representation> instead". Do you really think that would have 
been a serious solution?

I'd say that we are in a chicken and egg problem: we don't have users for this, 
but maybe because we don't have the feature. We already have internal tools 
that are using this feature, and have lots of hopes it will simplify some of 
our more complex internal CI and debugging processes. We plan to open source 
all of this, because we also believe that will also help others with the same 
kind of issues. But I agree that we might be wrong.
