The HTML5 placeholder attribute will indeed standardise its use and will negate the need for JavaScript to handle placeholder behaviour. 

Irrespective of this, consideration must be given to older/non-modern browsers and older screen readers, so bringing it back to the lowest common denominator, i.e. raw HTML is the best bet. 

Ensuring that labels are always in place and appropriately associated with form fields will provide a base layer and then titles and placeholders can be used as progressive enhancements. 

As the major screen reader vendors get most of their income from government programs supporting VI people in employment, but with 67% of VI people of working age in the UK being unemployed, technology adoption and particularily mainstream screenreaders are cost prohibitive. As there is no provision for those not in education or employment, screen reader hand me downs that rely on older browsers are being utilised by many VI people, thus the importance of this approach.
