Yeah, I guess that’s true. I wasn’t reading closely enough. I’ve just seen coders try to remove all decorations, and focus outlines and whatever - because they think they detract from the visual aesthetic of the site, not realizing that they’re making it more difficult for humans to use.
But you’re right, a group of social media, email, phone, etc. icons - that’s so common that it’s not going to confuse anyone, and would probably look cleaner. Some hover effect should be good enough.
