The share button on the post actions has been outfitted with new functionality: it will now copy the url of a post directly unto your clipboard, skipping the original share modal.
I have no strong objections either for or against, but based on that other topic, I would say the decision of having it as a per-user setting or anything else relating to it, probably exceeds this small component. Meaning, I’d prefer this component to do what is expected based on the site settings and possibly on the future user setting.
