Surely you would want to support Wine and not ReactOS?

The only advantage of ReactOS over WINE is that ReactOS has Windows 2003 compatible kernel. This means native Windows drivers, and faster emulation of some features.

However, a few decades from now, there will be no devices left which have Windows 2003 drivers. And hopefully CPUs will become faster, so Wine overhead will be negligible. And I doubt all the new devices will have ReactOS drivers.

Rather than keep going on ReactOS, I would much more prefer people making wine better.
