If it only means people can go to Switzerland and know on their return they won't be prosecuted, it'd be a step forwards.
My DM died in the manner she most feared - to an aggressive dementia that went from compus mentis in 2014 to catatonia in 2016. Eventually after breaking a hip and it not being detected for 2 days, she was admitted to hospital where they basically starved her to death.
I don't really go for vows and all that frippery, but I'll carry the weight of not being able to fulfil the vow that I would never let her end like that. Who knows what might have happened if it had been 2024 instead ?
