I'm not sure I see a use case for this, when do you compare 2 values and
replace one of those values with the result of the comparison? I've
literally never done that.

Again, why would you do this? How often are you replacing the contents of a
variable with the results of comparing it with something else?

$c = $a === $b;
$c = $a <=> $b;

That seems to be far more common if assigning the results to a variable at
all (which is itself not that common for comparisons in my experience).

Thanks for bringing this up, but I don't see the consistency argument, and
I don't feel like its normal use cases at all.
