Windows drivers can actually use more than 8KB. So in some situations,
you're already screwed.  There are already cases where vendors customer
service are now telling people "Use ndiswrapper" when people ask about
Linux support.

If we continue down this path, we'll have no native wireless drivers for Linux.
The answer is not to complain to linux-kernel for breaking ndiswrapper,
but complain to the vendors for not releasing specifications for
native drivers to be written.
