The quickfix window does not close with the window that it was opened for

The quickfix window that I get with `let g:validator_auto_open_quickfix = 1` when opening a file does not close when I close that file, resulting in me having to close that, too. Seems unnecessary. Never had to do that with syntastic.

Is this project still alive?
Or is w0rp/ale the one to use now?
