if they're good relationships, they will understand
Sure, what about not "good" relationships? What if you meet a new person and they say "hey, you seem like a cool person, we should get together again, what's your #?" and then you launch a tirade about the oligarchy and Edward Snowden and these people suddenly don't want to talk to you ever again.
I've said this before, but the way I handle this is a sort of self-hosted linktree style site: firstnamelastname.com, that has all of my contact info, in order of personal preference, and let them choose. That's about the most I can commit to.
