We have a saying at Mozilla: "Don't break the web."
If a browser vendor removed ASI support from their ES engine, many
existing sites would stop working. Their users would switch to other
browsers.

Most ES runs in browsers. If a browser shows a warning, it shows it to
the end user of a web site--the wrong person.
To put this another way, if a browser started showing warnings for
ASI, their users would be informed that many existing sites are
deprecated productions or something. They would switch to other
browsers.
