Margaret Stohl has stated that it's MCU canon, I linked the associated tweet on the Black Widow: Forever Red during the discussion three months ago. In virtually every comic book instance we consider Q&A with the writer as a reliable source for assigning realities on the wiki, so I personally feel it's a settled issue until subsequently contradicted, similar to official games being canon until otherwise preempted.
