It seems Policy supports this. I asked on #debian-mentors, and Paul Wise 
pointed me to http://wiki.debian.org/EmbeddedCodeCopies

Policy 4.13 says in http://www.debian.org/doc/debian-policy/ch-source.html

4.13 Convenience copies of code

Some software packages include in their distribution convenience copies of 
code from other software packages, generally so that users compiling from 
source don't have to download multiple packages. Debian packages should 
not make use of these convenience copies unless the included package is 
explicitly intended to be used in this way.[29] If the included code is 
already in the Debian archive in the form of a library, the Debian 
packaging should ensure that binary packages reference the libraries 
already in Debian and the convenience copy is not used. If the included 
code is not already in Debian, it should be packaged separately as a 
prerequisite if possible. [30]

This seems to apply here. The proviso "unless the included package is 
explicitly intended to be used in this way" is apparently intended for 
cases where the included library does not exist in a separate standalone 

If you guys think pointing CCL to the external Debian ASDF is reasonable, 
I'll ask upstream. Let me know.
