Sure but given the description of ChkTag and given the new exceptions and interrupts model they established with FRED, I don't see ChkTag being anything other than an MTE-style lock-and-key color tagging solution. The press article is just saying what the EAG is working on next now that they have shipped FRED, ACE, and AVX10. ChkTag is the current top priority item on the EAG's list and the standard for it should be finalised/released some time in the next few months. What they have done publicly so far is to say that ChkTag will be part of the ISA standard, they just haven't also revealed the details past that.
