Why is it a problem?  There is no guarantee Wine will be run with the
same --winver next time, so the "boot" utility or startup code has to
handle both idiotic mechanisms.  It is not important to _me_ that Wine
should be exactly as Windows, only that it should work well.

If an app that people find useful refuses to work at all if it finds
functions that it thinks should not be there, I guess we might have to
cater for it, but I'd rather not.
