Visualization license and multiple workers on same machine

Did PTC change how licensing works for multiple Creo workers on same machine?  We previously had  1 PROE_FoundationVis license for multiple workers set up on our visualization machine for many years as directed both here: https://www.ptc.com/en/support/article/CS29308 and here: https://www.ptc.com/en/support/article/CS473636 but when our contract was renewed, it seems PTC removed the  DUP_GROUP = "UHD"  directive from the PROE_FoundationVis license (as well as our Creo Advanced and Creo Advanced Professional licenses), and now each worker seems to pull a license.  That directive allows “Same user on same host and same display consumes one license even with multiple xtop processes” -- Found out the hard way when our extra workers went to start up and I got 1200 emails informing me that my CAD worker failed to start.  Anyone know if this was intentional on the part of PTC?  I have a case open - and I tried reaching out to License Management but got disconnected after being on hold for 20 minutes.
