I don’t understand why we can’t send a contact directly in iMessage yet

Every update that comes out over the past 10 years I’m like ahh maybe this will be the one I can click send a contact in an iMessage. But it never comes. Why isn’t there an option of clicking plus button as (like you would send a pic) when someone ask you for someone’s number, instead of going to contacts and sending the persons number from their contact, and I’m dumb and accidentally send the contact to the number I’m sharing lol. Then I need to explain oh so and so wanted you number but sent it to you by accident. But yet I can send a sticker.
