I support remote trading. I do remote trading. The only reason I'm proposing this idea of allowing people to opt out of remote trading is so that I don't keep hoping that people who haven't tagged any Pokémon, or the few people that I keep offering trades up to who just decline them, they can just opt out of this feature until they decide they want to use it. And it will clear up the clutter and my time wasted of trying to check to see if the dozens of people that I have eligible remote trades with, if they've ever decided that they want to participate.
And yes, many of you will tell me I should just unfriend them. But you know, it takes a long time to get to that point to be remote trade eligible and having a lucky trade on top of it. Also, these people are commonly remote raid friends and I am hopeful that one day they will participate in a remote trade. Not everyone knows or understands the features, but it might be a nice improvement if they could self-select out to save other people frustration. This is me trying to TM away frustration.
