If we had rules, yes. But we do not have. That's like - I will rename
all variables because of some non-existing rules... There is no rule, no
coding style (except what I wrote)...

What do you mean - looks wrong? It's just a label which does not matter,
so how it can be wrong?

No, it just does not matter, so there is no benefit to change it, in my
opinion, if label is readable and follows generic convention
(underscores). Of course someone might treat its readability different
and maybe for someone the missing "s" at the end is important. I am just
saying that, unlike the node names, the label has little impact/effect.

However just be clear - this change also does not harm, so I am
perfectly fine with it.

Best regards,
