Hardware Transactional Memory, the end?

HTM on about the only platform on which it's been reasonably successfully implemented, namely Z, is going away.

On page 93 of:

https://www.redbooks.ibm.com/redpieces/pdfs/sg248951.pdf

"Removal of support of the transactional execution and constrained transactional
execution facility: In a future IBM Z hardware system family, the transactional execution
and constrained transactional execution facility will no longer be supported. Users of the
facility on current servers should always check the facility indications before use."

So introduced on the EC12s, and still on z16, but not long for this world.

IBM also removed it from Power10 a couple of years ago.
