... but your version always will read Carp.pm from disk, even when its not needed.

We can discuss whether this optimization is premature or not, but sometimes avoiding Carp could be explained... somehow.

Another example - when using DynaLoader elder Perl may times checked for $^O, like it could change during the run.

There are Yin and Yang - some people stuck unneeded modules everywhere for the sake of imaginary improvement of code readability, others send optimization patches, because otherwise using innocent module will result in some tens of unneeded PMs loaded.
It seems to me that if Ilya Zakharevich never send his optimization patches, then Perl could be as slow as Java...
