That may be true but I'm not sure it applies in this context. Another valid reason is because at a larger scale it is easier to get the dimensions to be within a fairly close tolerance of the counterpart and hence to get two parts that function well in tandem.
Matched pairs and current mirrors are exactly the right situations for this and so they tend to be oversized, even if that slows the parts down considerably.
Also, I've seen some people use 071s' inputs with no DC path to ground, and see their output slowly drift up/down because of tiny bias currents. Doesn't happen with 741s, usually.

Q12 is a common emitter amplifier with an active load, that feeds directly into a class B output stage (pullup is a darlington with Q5 and Q6, and pulldown is Q13, with Q7 being a current limiter). I've never used this personally (for good reason) but I remember my mentors telling me this causes horrible CO distortion.
The 071 is also "jellybean" enough; both are still currently used in modern designs because how dirt cheap they are.
But they are "high voltage", non rail-to-rail anything, so people tend to use more modern options for new designs.
They’re just horrid. Fine for noddy stuff like power supplies and PID loops etc though.
Much more performant than the 741 (might have to do with 2 things: the 741 came early and was one of the pioneers and it is BJT only)
It's also curious how the the big butterfly transistors are at the input, components with a big die size are usually big for a reason (usually power).
One extra fact, the compensation capacitors are more like a wrench on gears and actually make the circuit "worse" (it lowers the overall bandwidth). But it is needed for stability purposes because good amplifiers will have a tendency to oscillate by themselves.
