Personally I consider this a QoI issue for UAs.

There will be lots of web pages that won't support / use this
auto-rotation suppressor. UAs will need and want to let their users
deal with this.

The BlackBerry PlayBook for instance has an item for it: swipe in from
top right corner, tap the orientation widget, select lock orientation,
tap the application  content area, move on with life.

I'm not saying it's perfect, and I've been planning to write out more
detailed proposals for more advanced things, but sometimes adding a
web-API doesn't really help the user. This isn't a web page problem,
it's a system problem, and the user will benefit from having a
*single* and *consistent* method for addressing it across all
applications, native, web, and web written by other people who decide
to put buttons and widgets in places the user won't expect.

Disclaimer: while my employer isn't endorsing my opinion, I'm happy to
use its products.
