Humor me, and don't mix bitwise ops with logical boolean ops without
parentheses, ok?

And yes, the old code did it too, so it's not a new thing.

But as it gets even more complex, let's just generally strive for doing

(a & b) || (c & d)

instead of

a & b || c & d

to make it easier to mentally see the grouping.
