Interestingly, I don’t think that is true: cowbuilder installs
itself into the build chroot, and LD_PRELOAD after chroot(2)
uses the library from within (as it’s pathname based).

This is the reason that, when we want to use eatmydata, we have
to install it inside the base.cow as well, and that some pak-
kages spew out warnings about “can’t preload lib*.so” under
cowbuilder (kdepim3 is my example of today).

You can do that with cowbuilder.
