I thought of another solution that I add to the discussion, though I
am not a python-debian developer:

4) Use the tarfile module to handle the decompression. According to
   the documentation, it can also take a file-like object fileobj as
   input, and specifying "r:bz2" (or just "r" for compression-detection)
   is supposed to work on compressed tar files. (I say supposed, because
   I was not able to get it to work, but that might just be me.)

Of the other solutions, I think implementing (2) by creating a wrapper
file-like class around the bz2 incremental decompressor
BZ2Decompressor is a good and fairly easy solution. Although my
initial problem would be solved by (3) since I don't need access to
the contents of the deb's data file.
