I seem to recall that libuv is missing the length check, but otherwise lgtm

You mean a max path type length check? I don't think I see that this is an issue.

libuv doesn't check that len > 4, but since it uses wcsncmp (which stops at NUL chars) it should be fine there. It doesn't check len < 264 either, but I guess excluding actual paths with length > 263 that start with \\?\ is less of a practical concern?

Paths that start with \\?\ are extended paths and can extend up to 32 767 characters. So the len < 264 check should actually not occur.
