mfoltzgoogle has just submitted a new pull request for 
https://github.com/w3c/presentation-api:

== Adds steps for initiating presentation from default presentation 
request. ==
This PR addresses the issues noted in Issue #359 ("setting 
presentation.defaultRequest will have no effect" note is ambiguous).  
Specifically:

1.  It clarifies that initiation of a presentation from the default 
request must come from the browser "chrome", not from any action of 
the page.
2. It lists specific steps for initiating a presentation from 
`start()` that check preconditions, allow the user to select a 
display, and return a Promise.
3. It lists specific steps for initiating a presentation from a 
default request that checks preconditions.
4. It clarifies that user agents that do not support initiation from a
 default request should ignore any value set for 
`navigator.presentation.defaultRequest.`
