Its honestly not a big deal, its just something to go rename for no good reason. At least for my job, it took about only a couple man-days to get every mention of blacklist/whitelist renamed and the code reviewed.

The bigger deal for me was master branch to main. Broke every pipeline script we had, broke our backups, and it caused not one but two outages in production. I guess its our fault for not making the branch name maintainable, but its never come up before and will never come up again. I honestly think between all the work we put in to that change, we spent a man-year on that. Thats before the production outages. Devops sucks.

At least I got paid to deal with it.
