Really, I do not think there is a need for any SC or an extension that will require or mandate that one MUST use explicitly associated labels. When a label is explicitly / implicitly associated, clicking it has moved focus to the corresponding control. This is a UA feature that aids accessibility and documented in H44. So when a visible text label is present, accessibility advocates / consultants should urge developers to use the most appropriate technique that helps conform to all applicable SCs and helps the widest group of PWDs. Now one can rely on the minimum level as someone suggested in a previous thread and claim conformance with <p><input type="checkbox" title="send me a ton of email" />Send me a ton of email</p> but accessibility consultants must highlight the demerits of this technique and educate developers to use the right technique in the circumstances. If a custom control is used for which H44 cannot be used, and the control is labelled with aria-labelledby, will WCAG2 similarly require clickability of that label too? Will the UA need to implement this or will it become the duty of the developer? Compare this to SC 2.4.1. Ignore other SCs (like Level AA 2.4.7) and other sufficient techniques for the moment, if a skip link is used to claim conformance, the link needs to be visible / become visible on tab focus. The SC does not require the link to become visible. But, the test procedures for G1, G123, and G124 all require that the link either always be visible or be visible when the link acquires focus. Not doing so amounts to incorrect implementation of the technique and one cannot rely on that technique to claim conformance to SC 2.4.1. So should this "visibility" of the mechanism be written into SC 2.4.1? I think not. Sure one can use other techniques like headings and landmarks, but again, consultants need to point out that these will not help sighted keyboard-only users when one needs to install a plugin to make it work and they are not available for all browsers / do not work reliably.
