I don't think "language" has ever been part of an HTML standard.
So no way to deprecated it.

The reason is accessibility for people with disabilities. Without a
description,
images, video, sounds, and other content is simply not useful to people

accessible.
Don't forget that a text equivalent is also useful to 250 million mobile
telephone users as well...

You need to represent "&" as "&amp;".
