I was like "oh, I'm sure this is some temporary hack, it will be gone
by the end of the series".
It wasn't gone by the end.
There's two copies of that pattern, and at the very least it needs a
big comment about what this pattern does and why.
But other than that reaction, I didn't get any hives from this. I
didn't *test* it, only looking at patches, but no red flags I could
notice.
