Nah, reversible polarity. I hate that.
It's 2024
There's a lot of dangerous stuff coming from questionable countries that are referencing neutral in bad circuit designs. That can make chassis/buttons/exposed parts live if the polarity is set as such. Even worse, it might work great for a long time and then a diode or capacitor goes open circuit and suddenly something is live that wasn't before.
In a device I trust, sure polarity won't matter. But, there's a lot of bad stuff out there, and I really don't want to count on my RCD to stop the current before it's done enough damage to me.
eh if you buy weird mains-powered devices from aliexpress that elude import control, that's on you
