Yeah, I saw that and I've looked for clients and features but it's really quite difficult to discover them.
For example, the following XEP (XMPP Extension) talks about best practices for message threads:
https://xmpp.org/extensions/xep-0201.html
And XEP-0085 about chat state notifications has a section about threads.
https://xmpp.org/extensions/xep-0085.html#bizrules-threads
So probably your best bet is to look at the list of supported features of all XMPP clients and see which ones support XEP-0085, and then between any clients that support that see if they support threading.
