the suggestion wasn't mine it came from the WAI CG Consensus Resolutions on
Text alternatives in HTML 5 which contains recommendations on alt in HTML 5
[1].

"This report provides WAI consensus recommendations for alternative text
support in HTML 5. On January 14, 2009 the WAI-CG created a Task Force on
Alternative Text, to consider the various alternative text approaches
discussed over the past few years, and to develop consensus WAI
recommendations for appropriate handling of alternative text in HTML5. These
recommendations have been reviewed by the following WAI Working Groups:
Authoring Tools Working Group (AUWG), Protocols & Formats Working Group
(PFWG), User Agent Working Group (UAWG), and Web Content (WCAG WG). "


My changing my mind does not mean that the recommendation goes away.
