I realized today that the use of {!Opportunity.Link} tag in email templates basically takes the users back to classic because the underlying URL is the "Classic Format". Any idea when this will change? If there will be a Lightning option to do the same or if there are any best practices how to solve for it? Would hate to hard-code the Org base URL (like https://cs4.salesforce.com/{!Opportunity.Id}) which I currently see as the only option.
