Slightly off topic but....

This has made me consider a new related pattern for the Design Guide, 
though it might be useful as part of this Pattern/SC in order to to help 
clarify the difference between 'most important thing' and other content.

* Additional content that is off screen should be clearly signposted and 
easily discoverable.

The idea is not to hide content that is not the most important thing and 
is 'off screen' (or "below the fold" if you must use that less suitable 

I know people are now mostly trained to know a vertical scroll is a 
basic gesture and to use it to check for more content - but can/should 
we rely on that?

That is certainly part of Objective "Help the user find what they need" 
but will also help user avoid making mistakes through missing something 
they need to know yet is not deem 'most important' by the author.
