I am not in love with using bits from prefixes as semantic tags. However, having said that, I think it's a bit ironic that you're talking about wasting space with semantic bits, on the one hand, and talking about the need for a /48 in every home on the other. It would be perfectly reasonable for the ISP to specify that some of the bits in the /48 have semantic meaning, for example, and given that we think it's okay to give the home network a /48, we are hardly in a position to quibble about how the bits in that /48 are used.
