Hmmm... add such songs and rhymes as "London's Bridge", "London's Burning", "The Grand Old Duke of York" and "Oranges and Lemons" and you've got commentary on other historical and social phenomena that aren't particularly linked to active sedition, as such... but, definitely aren't all that glowing, either. 
For more northern takes: "Bobbie Shaftoe"subtext is rather dark, as is "Bye, Baby Bunting"subtext and "When the Boat Comes In"subtext. And, for pure squick, there's always "Ring-a-Ring-a-Rosie" (even though that is probably made-up squick, that somebody went looking is still... a bit scary).
And, you left out a biggie in your seditious list (in this case, counter-sedition): "Please to remember the fifth of November..." 
The British: we like to introduce children to the harsh realities rather early. But, packaged in a nicely turned nonsense phrase. ![[lol]](https://static.tvtropes.org/pmwiki/pub/images/lol2v12_4863.png "[lol]"){kind=small}
Not our fault if we forget what was meant along the way...

It is rather odd when you think about it, isn't it?

Nah... it's preparedness training. "Politicians suck (and have done for centuries) and life is generally tough. But, you can make fun of it all and still find something to enjoy along the way: don't give up. Don't expect sunshine and happiness every day, though." 
Germany has some pretty interesting stories that follow the same lessons. They're not as gentle or tactful as the English in terms.
The English have always had the ability to talk about everything while still adhearing to very specific rules about how the conversation must go. It's very interesting.

For some reason, I'm just now appreciating how many rhymes and songs that every English-speaking child knows are tied to English sedition. "Sing a Song of Sixpence" was against Henry VIII; "Mary, Mary, Quite Contrary" was against Mary I; "Curly-locks, Curly-locks" was against Cromwell; "Rock-A-Bye Baby" was against James II and the Stuart succession; and "My Bonnie Lies Over the Ocean" was against George II. And these are just the ones that spring to mind.
The sedition in question, you'll notice, was not always successful. "Bonnie" in particular is unsuccessful, blatant, and represents an all-round bad idea besides, and yet it's just this kid's song that everyone knows, usually free of context.
I'd say the propagation of these memes suggests dissent is a pretty integral part of English-speaking culture - kick ass - but I really can't fathom how they reached every nursery.
