In general I don't think our success criteria are guilty of this,
though anyone who thinks they are is welcome, indeed encouraged, to
point out places where it occurs.

The other issue to bear in mind here is that WCAG also provides the
basis of the requirements in the User Agent Accessibility Guidelines;
the priorities in WCAG have a significant impact on the requirements
and priorities of UAAG.

Thus if we were to set priorities on the basis of what is commonly
implemented, the effect would be (1) that authors aiming for level 1
conformance would not implement them; (2) that they would be of lower
priority in the User Agent Accessibility Guidelines and the Authoring
Tool Accessibility Guidelines; and (3) because of (1) and (2), user
agent and authoring tool developers would be less inclined to
implement them, resulting in a self-reinforcing cycle of
non-implementation, independently of other motives that are likely to
influence developers.
