FWIW, many new specifications are hitting issues like this (well…
at least Web Animations!). It’s a pain that new classes can
clash with existing content, but I think we have to act
as if the future is bigger than the past and thus pick the best
name for the job.

As someone else said, the rule of not injecting into the global
namespace from a JS library has been known for a few years now,
and if you’re still not doing it you’re asking for trouble.
