Just because the host addresses are theoretically valid doesn't mean that using them is a good idea. Those two addresses constitute less than 1% of a network's addresses, and are very simple to configure out of your DHCP servers, etc. Again, the likelihood that these addresses will cause problems or experience connectivity issues is a far greater concern than the gain of less than 1% of usable address space.
