This change is probably ok. Assuming for the sake of argument that I
don't have access to CodeWeavers' internal bug tracker though, why
would we want to do this?

It turns out that D32_UNORM is never supported on d3d in practice.
Exposing it might confuse applications, which is exactly what happens
for the Steam version of Metal Slug (1, 2, 3 and X) and other games
(mostly other NEOGEO ports). There are a number of issue reports for
Proton related to this, e.g.
https://github.com/ValveSoftware/Proton/issues/1173.

Well, yes, but the point is that that kind of information should be in
the code. See also e.g. the comment at the top of
format_texture_info[].
