I concur with you, this is really annoying.
Since quite some time I have a local squid caching all of my http so I
don't have that trouble anymore, but I can see how I can't ask everybody
to spare 150 GB of disk for a squid cache like mine :D

Yeah, indeed.
I'm not aware of any way to tell debootstrap to use an apt cache, also
consider that debootstrap doesn't use apt at all for its job.
This is further complicated by the fact that a user could specify its
own debootstraper.

rather than reassigning what is needed is a new bug asking for a way for
specifying a cache place for debootstrap.  Could you perhaps file one
describing the needs (in particular, it would be handy if just passing
and apt cache directory could be enough for it to try it out).

In conclusion, I have no path on how to progress with this bug.
