I don't think this OS check is appropriate. If we want to add a new OS to WST
later it will be hard to track down all these conditions. We *maybe* should add
a new flag for WST, but I've had a lot of trouble with those in the past (if
needed through a lot of the codebase). I'd rather just leave this open -- it
doesn't matter if it's registered on other platforms (it just won't be used).

Done.
