I wouldn't say shouldn't - they are free to do what they want. But this is a blog post about something that can trip you up that the docs highlight - which the author calls a "heisenbug". The author doesn't even have a suggestion for the docs, which already calls out the problem they encountered, they just note that there are helpers for this problem (which is true). The point of my comment is that subtle, non intuitive things like this are all over Python and, while this one is particularly bad, this blog post makes it seem like more of an aberration than it is.
