No, it is not support of RFC 8315, but only the addition of an easy 
check that these header fields are present only once, if any, when a 
user posts an article.

Currently, if you want INN to support RFC 8315, you need using filter 
hooks, like this one for nnrpd (page in German):
 
https://netz-rettung-recht.de/archives/1473-INN-Cancel-Lock-und-Cancel-Key.html

INN does not natively implement RFC 8315, but can have the feature 
through filter hooks.
I hope to implement it natively for INN 2.7.0 (or 2.6.5).
