Web Components indirectly codifies the notion that hyphen-containing elements
are open as extension points and will not be overtaken by the browser in future
(minus a small, specific existing list):

This should be made explicit in the HTML specification, and extended to
attributes (also with a list of exclusions). This should help stop people from
using data-* for standards that build atop HTML.
