I'd agree with that. Now, I would also say if we need something that
depends on a newer version of _WIN32_WINNT that proves to be trickier
or even not possible for older versions, there could be an argument
for dropping older versions, even in the back-branches, if the problem
to-be-fixed is bad enough. In short history, we've never had to go
down to that AFAIK, though.
