At first read it looks interesting, and can definitely see that a lot
of thought was put into the design. There have, however, been a number
of previous attempts at alternative compact binary representations (or
at least discussions) that did not seem to really go anywhere. What is
the current implementation status of this? Are there implementations
available or any existing plans to use this new format in a specific
app or spec? I'm largely just curious about the context and motivation
behind this...

The design goals for the format are listed in the introduction; most notably, code compactness is considered as important as message compactness, and we think we got a lot of the latter with no sacrifice of the former.

Given its applicability to protocols across the Applications area (and actually across the IETF), we think this would be an appropriate to be an appsawg work item if others here think so as well. Please let us know what you think.
