No, this has not been changed, and I will fight hard to keep this. Actually I'm trying hard to get this fixed for the non-conforming architectured (ARM, MIPS, ...) which I consider broken.
It's not a matter of making use of all the additional memory; it's more a matter of not having an unaccessable region in the middle of the RAM block. There are a *lot* of different board configurations and a lot of different complex systems that load more than just a linux kernel.
ACK. And there are even systems which don't run Linux at all.
