I believe today you just say "hey, the drop is ready" over Signal.

Do you also send "the drop isn't ready" on other days? If not the fact that you sent a message tells the attacker everything without knowing the content.

Also can anything be inferred by the length of the signal message? Do they pad they out or will all of the sudden sending a 2kb vs 3kb message give you away that something is different?

Personally if my life is on the line, I'd stick with the shoelaces.

I assume that 99% of the point of techniques like in the article is to make the communications graph unobservable. If two people have regular communication over Signal, and one is suspected to be a mole or spy, then the other one is suspicious too. But shoelace patterns in a busy city aren't traceable like that.
