Assuming this will let us see how man async as well as sync requests are made.

It'd be awesome if we could get a count on how many sites out there use sync XHR, but I don't see a way of doing that without effectively sending the domain name of the site to us, which would be terrible privacy.

This counts all the open() calls, and either increases the async bar (0), or sync bar(1), so yes
it is easy to check how many XHR open calls there has been, and how many of those have been sync.
