If your definition of "safe" is so strict that it declares that's not safe, that's fine and your decision, but it's not a definition you can live by. You're not actually holding your actions in your life to that standard, because you can't be. It's fundamentally broken to do risk analysis without considering the possible benefits as well. Otherwise you end up with the answer to literally everything being "It could be harmful", with no countervailing possibilities, and your heuristic says "no" to everything, including doing nothing. You can't live that way.

In any normal sense it is safe.
