Yes, although I'd like to think of it as a "syncing" operation, rather
than a simple pull. That is because you need to handle all the usual
"directions" and details of (one-way) syncing, namely:
- pull in new stuff from your "upstream"
- delete local stuff which has gone from upstream
- be able to do both incremental runs and full runs

An annoyance to overcome is the differences existing among: 1) source
name and version (with epoch), 2) .dsc name (without epoch), 3) root dir
of the unpacked source (which is not granted to have a specific name).
It's all trivial to deal with, of course, but it's something that anyone
having to implement something like this will have to deal with, and
hence a good target for factorization.
For my use cases, I'm not really using any more package metadata than
the above (in particular, I'm not using any information about binary
packages and therefore I don't need any architecture related information
either). But I can easily imagine others needing more metadata than me.
On the other hand, once the root dir of the unpacked source package is
known, it's easy to parse debian/control there.

OK, thanks for clarifying this.
Cheers.
