Agreed. Annoyingly the author does split up a very core idea to the next paragraph:

> and we should be transitioning to even more secure passphrases. [newline] Or does it? Let's go into what LUKS is doing in the first place.

That sentence really should have been put into the introductory paragraph, instead of being the start of the 2nd.

Disagree, long paragraphs are more annoying than breaking up thoughts like this. I think it's reasonable to expect a reader to continue to the next paragraph, and corrosive to start writing for poor readers (distracted, skimming, etc - let people who do this bear the risk and consequences of their actions rather than changing writing to make this behavior less risky)

> absence of any sort of opsec failures

There is no such thing.
