I think the Kenwoods did.. I tried it a couple of years ago by relaying 
a maritime DGPS beacon stream into the local 2m APRS channel. And indeed 
I got a DGPS lock on my GPS receiver connected to the TM-D700.

But anyway why do we need to remove something that doesn't really cause 
problems from the spec? So that Bob's aprsdos can fit into 640k of RAM 
and claim full compatibility with every aspect of APRS? I'm not saying 
we couldn't/shouldn't remove the feature, just wondering the rationale..
