I think not a safety hazard if used as intended, but mine does appear to add a bit of flex.
I have one on my folding bike. That particular one might be unsafe because I put a quick release on it, that makes it easier to store the bike when I fold it. I am quite sure that the stem manufacturer would issue me a stern warning if they saw the quick release on their stem.
