A consideration: IMHO, in practice, it would make sense to limit this to multiplexers.
For other expanders (MCPs and, even if not [yet] foreseen, shift registers/SPI MCPs, particularly if chained) reading one input directly would mean reading all their input set, which basically defeats the purpose of having a quicker direct read.
