Feature or enhancement

The reason why .exe & co are mapped to octect-stream is likely for convenience (the IANA type for .exe is https://www.iana.org/assignments/media-types/application/vnd.microsoft.portable-executable)

That seems like a bug, the addition of .exe (1997) predates the official registration (2015) of the application/vnd.microsoft.portable-executable mimetype.
