You can specify limits during compression, so the question is should we do that
so that hosts with N MB of RAM can decompress packages?  Do we retain the
compression ratio over bzip2 if we limit compression memory to 512 MB so that
decompression would be possible with, say, 128 MB?

According to xz(1), in its default mode (-6), xz uses ~100MiB for
compression and ~10MiB for decompression.
That seems to be acceptable.
