Hopefully they stick to their guns, in fact, would be much better if the Paladin simply has to be LG.
If certain actions cause you to lose your mechanical abilities, I don't see what the difference is.I guess I just never saw the alignment requirement for playing a paladin as a "mechanic" per se. To me, it was a defining feature of what the class itself; exemplars of the Lawful Good alignment is what paladins are. Mechanics are things that affect die rolls and numerical modifiers - paladins ceasing to be paladins if they violate their nature as paragons of Lawful Good is what happens if they act against their fundamental nature.
I find it weird that they want to allow evil Paladins, but their adventures strongly assume good-aligned PCs.

My point is that wondering if it's a mechanic is a weird bit of navel-gazing with no discernible benefit.But those actions are completely under the player's control (notwithstanding being compelled to do something against your will, in which case it's usually easier to atone for it), rather than being dependent on a mechanism or modifier.
