Please don't add this! I hate sites that decide when I get a new window (which my browser turns into a new tab). If it's a normal link, I can click it with my middle mouse button to open in a new tab on the background. I use that feature all the time.
But if the website decides for me, I can't use a normal click without getting a new tab, which always results in me closing the initial tab (by clicking my middle mouse button on the tab).

True, phones are annoying. But please don't adjust desktop behaviour because of limitations on phones.
