Though I believe browsers will soon have much more pressure to support
multiple ranges as a matter of course, as increased design with
Flexbox and Grid will mean that highlighting from one point to
another, in the world of "a range is defined by two DOM endpoints and
contains everything between them in DOM order", can mean highlighting
random additional parts of the page that are completely unexpected.
Switching to a model of "visual" highlighting for selections will
require multi-range support.

In other words, it'll switch from being a rare thing to much more common.
