Comment (by adamsilverstein):

 > Could you open a separate ticket for your PR? I think it's worth
 including in 6.3.

 I opened https://core.trac.wordpress.org/ticket/58480 as a follow up to
 inline the styles, making them non blocking.

 Regarding the performance benefit, the biggest difference will be when
 network conditions are poor and the browser has to wait for the external
 http request to complete.
