I see, thanks, this curiously "mildy" (or perhaps, increasingly/incrementally) incentivizes most of these linux/posix/unix-"native" FOSS projects to no longer provide separate "Windows builds": simplifies code-bases, deployment, documentation, support, everything. But if they still continue to do, they have just another "support/bug dimension" to deal with in addition to "OS" --- the old "Windows build" plus also now "X-ish build under Winbash". In another twist to this, this dynamic then might 'incentivize' users of those packages to upgrade to 10 when they wouldn't have otherwise (or switch to Linux for good ;)
