They seem to be targeting NT 5.2, which is indeed Windows XP, so it makes sense to also target that graphical experience in a sense.

5.2 is windows 2003 / xp-64-bit. XP is 5.1. 64-bit XP was based off of Windows 2003 code base. All are out of support at this point. Doesnt seem like MP or 64-bit is supported per https://reactos.org/wiki/AMD64.
