It is a legal requirement to provide equal access to all features and information for people who use accessibility features. Any non-trivial deviation from this must be declared in an accessibility statement, or the site owner risks legal action and large fines.
100% is not hyperbole, even though ”not exist” is.
As someone who has led WCAG remediation projects, I can firmly assure that it is hyperbole.
100% “accessible” is meaningless: full adherence to what standard? 2.1 AA? That’s an incredibly high bar, and would require constant vigilance and expensive audits on a rotating basis. Much of the guidelines are up for interpretation and can’t easily be expressed in a binary pass/fail besides.
