While I understand your request, I don't think the use cases you raise are
really compelling enough reasons to add a new element to do this. <br>
works, and people have already proposed ways to extend CSS to do
line-by-line styling that would work without an explicit line element.

Actually it's worse, </br> is actually handled as <br> in browsers, so
you'd end up with blank lines if we did this.
