Don't know if it is helpful or not for you to know.
But it seems that it doesn't give the warning in the front end for ordinary users, so in that sense it seems to work ok.
As an admin I get the warning on all pages, and when I save a page or post it usually works, but the page doesn't load after saving so have to close that tab and open the same thing in a new one.
Other only thing I've seen that doesn't work is to upload media files.
If I turn of the compatibility plugin when doing that type of editing it seems to work, then just activate it again when done uploading pictures etc.
Apart from this glitch it seems to handle most things with Event manager working together with WPML.
