In my perspective, this Linux subsystem are very useful for running server components like redis, or nginx which doesn't have official windows build. So you can develop server apps which will run on Linux prod, but develop it with Windows

Unless I can fire up windbg and point them at these binaries (which would involve teaching dbghelp to read DWARF, and be useful in its own right), I still don't see much of a point. I can always just use a lightweight VM, and paravirtualized cross-VM filesystem access already exists.

You're rather presuming that one would use windbg. That's an unwarranted assumption, given that the hypothetical developer here who is developing server apps using redis and nginx "with Windows, for Linux prod" is likely to think of gdb as the debugger.

Of course, whether gdb would work is something that we haven't yet been shown.
