Boolean attribute oddity with relation to HTML5

[dead-claudia]

Would it be possible to make the empty string an alias for "true" (for relevant attributes) for HTML5 shorthand compatibility?

According to this React comment, every boolean attribute defaults to "false" if not present. However, from a quick search of the spec, some roles (e.g. role="alert") change the default to true (in that case, aria-checked), so I can see the value of a separate true/false that's more than just presence/non-presence. However, HTML5 idiomatically prefers the empty string for things that are conceptually true, and has a special syntax for that to encourage such definitions and usage. So would it be possible to accomodate that by making "" an alias for "true" for attributes that accept an attribute named "true" (provided it doesn't conflict with other possible values)?

While I understand the desire for this it is not something we can change at this point in time.
