There are some pretty useful abstractions and libraries that MinGW doesn't work with. Biggest example is the WIL[1], which Windows kernel programmers use and is a massive improvement in ergonomics and safety when writing native Windows platform code.
'MinGW' is not GCC; it's an ABI, and from the developer perspective it is also the headers and the libraries. You can have GCC MinGW, Clang MinGW, Rust MinGW, Zig MinGW, C# AOT MinGW.
if you want to link msvc built libraries (that are external/you dont have source), mingw may not be an option. for an example you can get steamworks sdk to build with mingw but it will crash at runtime
From the capitalization I can tell you and the parent might not be aware it's "minimal GNU for Windows" which I would tend to pronounce "min g w" and capitalize as "MinGW." I used to say ming. Now it's my little friend. Say hello to my little friend, mang.
