We should bring this up on the spec + working group first. 

Ilya, is there a spec bug for this or should we file one?
This seems like a general question for PerformanceEntry and not specific to NT2.
(I recall previous discussion but can't find the issue)

We should open a bug on NT2. 

FWIW, RT2 provides the resolved URL in name: http://w3c.github.io/resource-timing/#performanceresourcetiming. In NT2 we override that and report "document". 

Given that in NT2 we only ever report one navtiming entry, perhaps this is not a big deal and something we can live with. However, thinking a little bit ahead... We *do* want to expose other navigation requests (e.g. redirects) as separate entries, and when we do so, we need to expose the URL (which means name field should report URLs). Perhaps its not too late for us to make the change and make developer lives easier down the road..
