Isn't the stigma desired anyway? It keeps people from going through with it. That's why society deliberately creates and actively cultivates the stigma.
I doubt removing "committed" removes any stigma to seek help. What sucks about suicidality is that everyone is so sterile about it. Removing the word is more of that. IMO the sterility discourages the not-yet-at-rock-bottom suicidal from reaching out.
