Håkon Wium Lie, father of CSS and CTO of Opera:
It seems that proposals for presentational elements return every so often. The most recent incarnation is CSS Regions. One should not write “considered harmful” articles lightly, but presentational elements is not the only problem with CSS Regions. For those who believe in meaningful HTML tags, responsive web design, and compact CSS code, the introduction of CSS Regions is not good news.
Google apparently took note, albeit arguably for different resons. Hoping the other browser vendors will do so as well.
