It's a "simplified" schematic. Add up the poles if it were
implemented purely as shown, and you'll see why a zero is required
somewhere... for capacitive loads it needs to be associated with the
output configuration.

So LDO Designers aren't as stupid as might be assumed?

It depends on how stupid you assume they are. There are also some
mistakes that it takes very smart people to make.

In the past I have made some "do it your self" LDOs. It is very easy
to make them stable with any load capacitance you you accept a crappy
load regulation.
