Please don't put that into the files used to prepare content for dpkg
-s and apt-cache - that output is large enough as it is. A single step
like this could seriously compromise package handling on low resource
machines and push apt passed it's memory mapping limits again even on
more powerful machines.

... and that would be even worse if not isolated from the status and
cache information at the point where it is unpacked.

Wherever the data lives inside the .deb is not the problem. 

Where the data gets cached, copied, listed and parsed is likely to be a
major problem.
