Apparently the extraordinary demand for plungers resulted in better plungers, not in someone asking "why the heck are we so reliant on plungers?" and possibly making better toilets ;-)
Really it should be impossible to clog a toilet with poops alone.
And if you find yourself excreting an unusual amount in one sitting, or need to use an unusual quantity of paper, just do an intermediate flush.
I've needed a plunger once in the last 2 years of apartments (didn't even get around go buying one at my last one before I left)
I need that toilet brush every other day, it's a really gross problem, and I hate the idea of having guests and them having to choose between leaving a dirty bowl and whipping out my toilet brush...

I replaced the first one in 2015 and haven’t had any issues yet.
Pro-tip: the actual first thing I do when any family members or myself move into a new home or apartment is install a kitchen side spray in the bathroom as a hand-held “point and shoot” bidet. Those can be used to quickly clean in a contact-free way.
