I'd be curious to have a more in-depth answer to this, myself.

My understanding has always been that they check to make sure that what
they're signing is not visibly malicious, and in most cases also that it
can't chain to load something else (which isn't signed, and might be
malicious). Since the entire purpose of the shim - at least as I
understand it - is to chain to load something else, clearly either that
understanding is not correct, or they're making an exception for the
case of the shim.
