You could also complexity for the human reader. That's a point where
personal perception comes in, which needs to be taken into account.

It *can*, but not necessarily. I'd prefer leaving this choice to the
maintainer, as he's the one who finally needs to care about all the
code. Discussions about such choices tend to be pointless (personal
perception / taste isn't something that can be debated by argument) and
risks annoying people and waste precious brain time.

In general correct. But in some cases repeating a few words can make the
code actually easier to read (psychologic phenomenon - human brains work
very different from computers). This needs to be carefully weighted.

Theorettically, we could do this conversation with much less words,
using some purely logic language, similar to math formulas - but for
most people this hard to do. Therefore, let's make the code easy for
us humans and let the machines (eg. compiler) do the heavy lifting.

For particular change, I wouldn't really object, but I don't like it
so much either. Some your other changes IMHO do make the code prettier.

That's the point. Psychology / personal perception plays a big role
here. We can't deduce it by pure logic.
