Hi, I might be the one who made the other thread you are referring to dreambled. My two cents is that if you don't want to activate sneak attack, then attack in a way that wouldn't activate sneak attack. Get off high ground, don't be in stealth, equip a non-ranged or finesse weapon. There is no need for a toggle when the basic implementation of sneak attack, automatic or not, is itself a toggle. The default design of sneak attack should reflect how it's used the vast majority of the time.
Actually, I was testing in the game to see if sneak attack could be applied to non-finesse weapons, and it does. I don't know if they intend to change it later on but longswords are perfectly capable of sneak attacks, I don't know if this is due to them being a rogue proficiency, or if they allow the rogue to sneak attack with any proficient weapon as that would make Gith greatsword wielding rogues very powerful.
