This is unfortunate indeed, but somewhat owed to the fact that this was 
not encoded reliably previously, in other words, negations were 
sometimes erroneously allowed as each match checked for this themselves. 

With the move to the Guided Option Parser, negation became centrally 
checked and thus needs to be explicit mentioned. With the initial 
conversion to GOP, I may have missed adding XTOPT_INVERT in some cases 
because of that repetitive action.

Yeah, there are other extensions (xt_dccp) that I have come across in my 
audit sweep of all extensions so far.
