SQL Server trace flag 8721 - auto stats sync & async update info

Aaron Morelli (@sqlcrossjoin on Twitter) has a great collection of trace flags in the pdf linked below.  (Check to see if there's a more recent update, v6 was current as of April 2016.)

Trace flag 8721 is of interest to me when investigating ETL behavior.  A complex ETL could change stats numerous times for lots of stats keys.  Information for auto stats updates in addition to stats updates performed explicitly by ETL code can really help complete the picture of what happens during an investigation.

I found this post from Prince Rastogi where he walks through a demo of trace flag 8721 by creating a new table with a stats key, increasing the rows from 0 to 1, then executing a query that requests the stats.  Here's an important note: use trace flag 3605 (redirect some output to SQL Server log) together with trace flag 8721.

I had two questions, and answered them both by following the same process.
My first question: Does it still work in SQL Server 2016? Yep.
Second question: Does it capture both async & sync auto stats updates? Yep.
